Why Should I Learn React JS? Top 10 Reasons

Why should I learn React JS?

Which is a common question among most of the students.

So that in this article, I am going to explain

What is React JS?
What are the important features of React JS?
What is the feature of React JS?
How should I learn React JS?

So it helps you to understand the React Js and decide whether learning React JS helps you to decide your career path.

Let’s Start

1. What is React JS?

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called “components”. (Source)

Let me explain

When you open any website or mobile application then what you will see on the screen is called the front end of the application.

It contains toolbars, TextArea, various labels, buttons, social widget, Submit, and other components which show some information.

How will those elements be created?

We use HTML, CSS & Javascript language to design those elements.

You may observe that those elements may move from one direction to another, change automatically without reloading the page or changing your screen.

All these things are carried down by using Javascript.

So, If you want to add any additional features to your page or app then you have to write the Javascript code for every element on the page.

Which is a time-consuming process.

So to reduce your coding process you can use JavaScript Libraries and JavaScript Frameworks.

JavaScript Libraries: JavaScript libraries are collections of prewritten code snippets that can be used (and reused) to perform common JavaScript functions.

Whenever you need a specific function then you can simply add these libraries to your project. So that you don’t need to write code again and which will reduce your coding time.

Example of Javascript Libraries: jQuery, D3.js, React, Glimmer.js

JavaScript Frameworks: JavaScript frameworks are a full toolset that helps shape and organize your website or web application.

These frameworks work as the foundation for application development and offer readymade solutions for common coding problems.

So you don’t need to write coding for every function. The framework

If you want to add additional code to this framework, then you must follow the rules and regulations of the framework while writing the code.

Example of Javascript frameworks: Node.js, Vue.js, jQuery, Angular

React JS is a JavaScript library, which is designed to build the user interface for web and mobile applications.

This User Interface includes on-screen menus, search bars, buttons, and anything else someone uses to interact with a website or app.

2. Important Features of React JS

React JS is created by Facebook engineer Jordan Wake in the year 2011. And now it is maintained by all the open-source contributors, including Facebook.

Today, it became one of the top three JavaScript libraries and frameworks used by front-end developers. (Source)

Now we will see the feature of React JS

1. React JS is Simple & Flexible

React JS is simple and flexible. Once you have learned it, you create quality interfaces on any platform.

Even though it is primarily designed to create components for web applications. But now React’s popularity is grown, its ecosystem also has grown to cover various use cases.

Now you can build static websites, Mobile Apps, and desktop applications by using React JS by using additional tools.

2. React Has Facebook’s Support/Resources

React JS has a heavy backup from the Facebook group. They are using it heavily in the Facebook app, website, and Instagram.

That’s why Facebook is deeply committed to it. They use over 50k React components in their production environment.

3. Easy to Learn:

If you know the basics of Javascript then you can learn React Js very simply and build professional web and mobile applications easily.

Its component-based approach, well-defined lifecycle, and use of just plain JavaScript make Learning React JS very simple.

4. Native Approach

React can be used to create mobile applications. It extensively supports code reusability. It can be used to develop IOS, Android, and Web applications.

5. Data Binding

React uses one-way data binding. It uses an application architecture called Flux which uses a control point called dispatcher to control the flow of data to components.

It’s easier to debug self-contained components of large ReactJS apps.

6. Performance

React does not offer any concept of a built-in container for dependency. You can use Browserify, Require JS, EcmaScript 6 modules which we can use via Babel, ReactJS-di to inject dependencies automatically.

7. Testability

Testing ReactJS applications are very easy. React views can be treated as functions of the state. To manipulate the state we pass it to the ReactJS view and take a look at the output and triggered actions, events, functions, etc.

8. React is very scalable

The react JS is very scalable. The very first and main evidence of the React JS scalability is Facebook itself.

It’s made entirely on React JS and has over 50,000 different components. And it’s still growing without any performance problems!

9. React’s Performance is Amazing

High performance is critical for any web application.

The applications built with React JS give better performance compared to those that use other frameworks.

Because it uses virtual DOM, which means it doesn’t have to generate all the HTML files from the bottom to the top, whenever the change appears.

Instead, he looks for the differences between the current and the old HTML and updating it accordingly, making all the loading experience feels like a blink of an eye.

10. Development Speed

React JS is a developer-friendly application. You can develop web and mobile applications way much faster than any other framework.

The great advantage of React is that you can just code it once, and use it on any other different platforms. So you can build multi-platform apps very easily.

11. Backward Compatibility

React JS high backward compatibility. Whenever a new version of React is coming out, the public API remains the same.

So that you don’t need to write the entire code again. You can run the old code on the new version without any problem.

In other words, you don’t have to learn React again and again after every new launch. You can use your older version and remains compatible with all the new components.

3. Why Should I Learn React JS?: The Future of ReactJS

The world’s top and big companies like Facebook, Instagram, What’s up, Twitter, Microsoft, Yahoo, Netflix, PayPal, Imdb, Uber, Wix, Atlassian, Cloudflare, Slack, Dropbox, Salesforce, Airbnb, Reddit, BBC are using REact JS.

The future is 100% great due to the support of a substantial big Community from Facebook. The developers and businesses strongly believe that the ReactJS applications give them high performance and good quality for market reach.

More and more big companies are using React JS to develop their applications so that they can get high performance and good quality for market reach.

Now you can think and imagine the future of React JS.

Now We will see what skills do you need to learn React JS.

4. How Should I learn React JS?

The best way to learn React is to learn and practice by building some projects. Then only you can get understand the complete concepts of React JS.

Things you need to Learn before ReactJs

As you already know that ReactJs is a JavaScript library that is developed by Facebook.

The main purpose of React JS is to build fast and efficient web applications by using reusable components.

To learn and master the React Js skill, You must have proper knowledge of the following.
