6 Pro Tips from React Developers

If you’re new to ReactJs, you could benefit from learning from the success and failure from react.Js developers. Here are the 6 pro tips from react.js developers.

React Developers Pro Tip #1 

– Use the functional components, if you do not need internal state or lifecycle methods. Here’s a class-based component, that really ought to be a functional component, now, it’s a pure function that accepts props as this argument and returns a react element. The advantages of functional components are there’s less code so it’s easier to understand the component is stateless so you don’t accidentally store state on a component that you shouldn’t. The component is simpler to test, there’s no this finding and it’s easier to see when and where to extract smaller components which leads me

React Developers Pro Tip #2

– To keep your components small, small components are easier to read tests maintain and reuse, for example, a comment component, it contains a comment div with a user info tip inside of it along with the division for comment text and comment date but if I’m going to use this user info information during my application, I can extract this into its own component. In this case, a functional component is neatly tuck, the user info component within my common component and wherever else in my application that I’ll need it, since I’m now in a functional component I do not require the dots, so they’ll get deleted and if I wanted to make this even more modular I could take out this block of code make it into its own Avatar component, then switch this out and nest avatar, now I will have  my Avatar component within my user component, within my common component they are compact and very simple to read Reuse and maintain.

React Developers Pro Tip #3

Understand how to handle ‘this’ remember tip 1, since functional components don’t require this binding you’ll want to use them whenever possible but if you are using an es6 class you’ll want to bind this manually, since react doesn’t auto bind the functions within that component here are several methods for doing so.

One method is to, Bindin render. So this way is concise and clear and works, but it can cause a little performance issue because a new function is going to be called every time this component re-renders which could be very frequent. Another option is to use an Arrow function render. So this is concise and clear, like method one, but like method one it will also create a new function every time, this component renders another method is to Bind in the constructor. So this is going to resolve the possible performance issues of methods 1 and 2 – just don’t forget to call super here in the constructor, another method is to bind in the Arrow function of a class property. So this is much clean and readable and it’s going to ignore performance issues of methods 1 and 2 and avoids the repetition of method 3, please be aware, however, this method relies on experimental features and it’s not an official part of the ACMA script specification. You can allow experimental language features by installing and configuring the babel package and apps created by a create react app has many features enabled.

React Developers Pro Tip #4

Use a function in SetState, not an object. According to the react Docs, react does not guarantee that state changes are applied immediately, therefore, reading this state right after calling set state is a potential pitfall, because the dot state may not be actually what you think it is,  instead of updating state with an object we can update it with a function. Function will accept the previous state as its first argument, and the props at the time the update is applied as it’s the second argument.

React Developers Pro Tip #5

– Utilize prop types, prop type is a library for type checking props and it can help to prevent bugs by ensuring you are using the right data types for your props, it is an external library so you’re going to install npm or however, you prefer installing then import the library and add prop types to the component, set the data type accordingly and if it’s needed add is required.

React Developers Pro Tip #6

–  Use react developer tools, let’s take a look at the features, now looking at any web application built in react, we can notice in the react tab we can view the component hierarchy and if we were to click on a component, we can view the props as well as the state of that component so as you can notice this is a very valuable and very helpful tool to test and debug and really understand what’s happening with your app. If you have any more react tips, I’d love to hear about them in the comments.

Happy coding 🙂


React vs angular2

React vs Angular2: You should know the difference

React vs Angular2: In my previous article, we had a discussion on react vs angular right? Now we will discuss React vs Angular2. It is very important to know that, the right choice of technology always matter.  Having the experience to work with a variety of technologists, I am very much excited to help you on how to decide between angular2 and react.Js frameworks. Angularjs is an open source JavaScript framework providing everything needed to create a client-side or website.

Angular is a Google creation that was designed with simplicity in mind

React vs angular2

It is worth noting that its second version, unlike the first one, has got rid of all unnecessary complexity. The team of angular 2 developers has added native apps support, server-side rendering, and much more. We also cannot omit the fact that angular 2 performance increase dramatically.

First of all, angular is a Google creation that was designed with simplicity in mind. It means that angular will not injure coders’ psyche while learning. Besides, many coders’ point out that if your angular code looks complicated  – you are doing something wrong. The popular websites built on angular we can refer: GoodFilms, Freelancer, Upwork, etc. ReactJS is a JavaScript-based open source library with the JSX compiler. This library is mainly focused on the user interface allowing to create reusable UI view components. From the technological point of view, react-based solutions are feeling friendly. Their performance effects ability is high, so popular websites built on react.js we can refer, to Netflix, Sidley, Walmart etc.

Technologies Comparison – React vs Angular2

Now, let’s dive deeper into details that are quite important during technology selection. One should be acknowledged with the kind of license that framework is disturbed under. Several licenses are much flexible to work with and one can use them to create commercial apps without any problem. However, there is a variety of license that doesn’t give you such a freedom of action.

Angular and react are both open source with no restrictions towards the usage, angular uses MIT license against three closed BSD used in react. However, the only visible difference of BSD is a ban on usage of a right holders name for advertising purposes.

Model, View, and Controller

react vs angular2

The model-view-controller pattern allows splitting the project data into three components: Model, View, and controller. This way, the magnification of each component can be conducted independently leading to tighter code and increasing the quality of the final product. Among all the angular features, the availability of MVC patterns out of the box is a significant advantage to reactJs.

Talking about angular, worth to mention its ease of display templates writing. Having really straightforward UI for your data, angular allows you to get the end result with a more intuitive approach to the user interface that demands less code and seems to be more obvious.

Document Object Model(DOM)

In that case with reactJs, it needs some special functions in order to manage data display. Mostly it means that you should define the way your data is represented before it will be coded into the DOM. That might cause a disconnect during its attempts to determine how a particular element will be rendered. Angular uses two-way data-binding, with its help, the framework is able to connect DOM model data via the controller.

In a nutshell, when a user interacts with inputs and provides new value to your app not only view can be updated but also the model too. Therefore, you do not need to write any method for tracking these changes within the application.

However, this approach affects performance since a watcher for each binding is created. React uses one-way data-binding, where the flow data is directed only in one way. Due to this, you will only be aware of a place where your data changes. This approach is much easier to debug when it comes to large application.

Angular creates a watcher for every binding in order to track all the changes in the DOM. As soon as the view gets some updates, Angular start comparing obtain values with the initial ones. So that, Angular 2 performance may cause some problem when it comes to massive apps.

ReactJS experts have introduced the virtual DOM idea that allows creating light DOM tree saving it on the server. Every time a user interacts with the website, for example, filling the form, react creates a new virtual DOM for comparing it with a previous one. After the library has found all the differences, between these two models – the virtual DOM model will be revealed. This way reacts performance increases when it comes to big amounts of data since there are no watchers.

Angular vs React

Angular vs React explained in detail..!!

Angular.Js vs React.Js

The benefits of developing with JavaScript frameworks, like angular or react. Angular vs React: the next question that usually comes is what is the best one to use what and should we use for the business or which is the most recommended one in general and unfortunately, it’s not an easy answer because a lot of these frameworks are a very similar concept that makes scalable web application possible.

Imagine, we go to a car dealership we ask the salesman what’s your best car, well that’s going to depend on what we need, something the great gas mileage or a perfect towing capacity, all the cars in the lot will technically help to take us to travel from A to B but they’ll do it in multiple ways and we might like one versus the other based on those specifications. So, it’s very similar with JavaScript frameworks a lot of them are based around componentize development making scalable large applications easier but they’re going to do it in different ways and some developers really like angular & some really like react but again both are great solutions to make large web or mobile applications. Ultimately, we encourage the readers to do a test drive some of these tools and figure out the best solution for yourself.

Differences between Angular & React.

Now, the differences between Angular and React. Angular as marketed a complete framework for either web or mobile it takes over the assembly line with everything we needed to develop – large-scale applications out of the box and it’s built on typescript, a superset of JavaScript which can be great or terrible depending on who you ask typescript is a language that actually compiles down into standard JavaScript. It necessarily gives us the features of the future to use at present as well as optimizing our code for the browser because once new JavaScript standards are defined browsers still have to implement those specifications or make them available to use typescript.

Let us use these features and then worry about spitting out code, that the browser will understand, it’s a strongly typed language that allows developers to specify datatypes and strict contracts between various pieces of code. Those who come from a Java or C sharp background might really like typescript as it shares a lot of common features. Now, there’s a ton of great things in typescript that we can’t possibly cover in one blog, so we’ll be diving deeper into these as we continue to pin down more blogs, but one of the greatest benefits about typescript and having that compilation process, that is, we can catch a lot of Arizona code before even running our app, if you’ve ever worked with JavaScript you can understand the pain and easily misspelling a word that crashes your entire program and you can wait several minutes hunting for a bug that was all because of a silly mistake. Let’s be clear, typescript can be used with a variety of tools.!

What makes interesting about angular.Js?

Angular vs React

What makes interesting about angular is, they really treat it like an A-class citizen and you’ll understand all the documentation defaults around typescript.

If you’re using react.js and you want to use typescript you might find it a little difficult to find documentation or others doing the same thing. Need Developers? Hire Top ReactJs developers

Main differences between the ionic and native script

Angular vs React

To develop your mobile applications in angular there’s a couple ways we can do, we can use the ionic framework which is a truly hybrid approach making cross-platform apps that uses the web browser within a native app container or we can choose to use native script which is a truly native application with native UI accomplishing 60 frames per second.

These are the two main differences between the ionic and native script and there’s definitely pros and cons to both approaches because this is an introductory blog and I will again save that for later stages. One of the major differences between angular and react is that Angular is indeed a full-fledged toolkit to create your applications out of the box, angular has solutions for routing accessing data services, templating and more. I think the biggest advantage with angular is that everything is right there for you to use and this is going to provide a lot of consistency.

Reasons to don’t like Angular.Js

Angular vs React

Now, one of the biggest cons developers probably don’t like about angular is that it is indeed a box you are operating including the new libraries. There’s absolutely an angular way. Now, the question is can you use angular without typescript? Sure! You can, but it’s actually not used widely and so if you really don’t like typescript you might be best just choosing a different framework maybe something like react and the question that all of the managers and CTOs want to know, who’s using angular today?

Well, the big names like NBA Sears, the NFL grub hub, for just a few and for a more list of companies using angular. A full listing of more showcases, react on the other hand takes a different approach to all this because react is just a piece of the puzzle of selling point and its use as a virtual Dom in the emphases on application state, now you’re probably asking yourself what’s a virtual DOM and to understand that I have to write about the regular Dom, the document object model or Dom is the view representation of all your code it takes our HTML and JavaScript to create what we see on the real page. Dom was never built for the dynamic web apps.

The previous websites were static content and general text living on a page, nowadays we are really pushing the dominoes since it was not designed to do so. Searching for Best ReactJs Development Services

How React.Js resolves issues can’t be done by Angular

React went about resolving this performance problem by removing itself away from the environment. With react you work with an object representation of the Dom & react maintains two snapshots, an original and one of the updated changes. That compares the two, to find the difference updating that small piece of code that actually needs to be changed rather than rewriting the entire HTML document.

What ends up happening is an extraordinary performance boost as we’re not forcing the whole browser to repaint itself, every time there’s a change again there’s a lot more that goes into this process. One of my preferred things about react is the focus, it has on application state it’s an object, that controls how the code or component renders and behaves.

One can think of state as a single source of truth for all the react.js components rather than keeping values and variables that are littered throughout the component or application, they’re continued in a single object that can only be restructured through a special method of set state & it’s similar to a private class with properties that get updated with a public method. At current, you still use variables in react but State is an object used for something that’s dynamic like the data that might change or maybe boolean values which they like to show or hide a loading spinner this makes it very easy to debug a react application.

React.js features Virtual DOM | State

One can always find an exact State to try to reproduce some bug or some feature. Since react focuses on these two features of the virtual DOM and state alone, its needed to fill those missing pieces like routing and templating. Fortunately, there are a lot of react.Js libraries out there to back this like the rack router and JSX JSX is not technically templating, but it serves and resembles alike properties and functionality tools like they produce rack tap and make this really easy to create a rack tap that already has all these pieces assembled for you in react.

We don’t really get a lot of that boxed with angular because it only governs the view layer with the state object and it doesn’t really care if you want to include additional library, one can easily snag a package off of NPM import an entry application and that goes downside with a lot of react apps, that can vary in their composition with multiple tools to accomplish similar tasks that might find to react.Js applications that look very dissimilar from one another.

When you are going to use React.Js know these tools and style opinions

Angular vs React

So if you’re going to use react it’s going to be really important for you and your team to get together and agree upon certain tools and style opinions within your business and just as a reminder we can accomplish numerous things that we get, an angular with type checking and additionally there are so many different react packages that again is very important to agree upon what we’re going to use and be on the same page within the business need and in reactJs.

We can also make mobile apps just like angular so if we wanted to make mobile apps with react.Js we would use a react native, we could technically use a native script but react native is really leading the charge and making native UIs for mobile devices. React native comes from the same people at, Facebook that gives us react and has a great ecosystem of third-party components if we wanted to take a more hyper approach with web views inside a native container we could use PhoneGap from Apache. In fact, this is what ionic builds off of and as far as who’s using react there’s actually quite a few companies you might recognize such as, Twitter, Airbnb or uber or Pinterest they’re all using racks somewhere in their product.

Airbnb: One of the Biggest react.js company

Angular vs React

Airbnb is one of the biggest react companies I’ve seen including react native. Now, if you’re using angular or you’re planning to use angular don’t let this discourage you because a cool name is not on your list. Remember, angular entirely rewrote itself from version one to version two, to be a huge scalable framework and it wasn’t really intended to do that with angular one but they pushed as far as they could take it and then they went back to the drawing board on angular 2.

Whereas, a rack has had much more of a steady evolution, since, it’s only focusing on the view layer in this state object. The other companies started off with, PHP or Ruby on Rails and they’ve been sprinkling react into their applications, so that might be a big-time reason why a lot of them chose react over angular, they weren’t rebuilding it from a start and eating a whole framework like that, I personally think one of the foulest things one could do is to pick one of these frameworks, because Company A or B is using it. Yet again, look at these frameworks, evaluate it for your own self and then make the final decision.
