Why you should Learn ReactJS in 2023


React was introduced to the world few years ago, and since then it has seen impressive growth, both inside and outside Facebook. New web projects at Facebook are commonly built using React in one form or another, and it is being broadly adopted across the industry. Developers and Designers are choosing React because it allows spending more time to focus more on the product development and less time spent on fighting and learning to the framework.

A React application is a collection of discrete components, each representing a single view. The idea of every individual view component makes it easy to iterate on product development because to make changes on a single view or component, it is not necessary to consider the entire system. When an application is built with React, the code is generally predictable, it is because React wraps the DOM mutative, imperative API with a declarative one, which raises the level of abstraction and simplifies the programming model. Moreover, it is easier to scale the application built with React.

The combination of React and the rapid iteration cycle of the web has enabled us to make some excellent products including many Facebook components. An amazing Javascript framework called Relay has also been made on top of React, which helps simplifying data fetching on a large scale.

Why you should Learn ReactJS in 2023

Short and Easy Learning Curve

Unlike some other JavaScript libraries where it takes a lot of time to learn about the frameworks, in React it does not take much of an effort to start building an application. React is comprised of many strong features. Readability is one of the greatest strengths of React. It is easily readable even to those who are unfamiliar with it. While other frameworks require learning many concepts about the framework itself, ignoring the language fundamentals, React does the absolute opposite. For example, let’s consider how different it is in React and Ionic (AngularJS) rendering a portion of an employer’s list.

In Ionic, it requires to use of the directive called ngRepeat. Let’s assume an array of employers. Each of them contains the following fields: first_name, last_name, is_married.

The target is to show only employers who are married. The following Figure 1 shows a screenshot of a function written in the Ionic framework.

As shown in Figure 1, a function is written called EmployerCtrl where it shows some specific information of the employers.

Figure 2 shows a screenshot of a directive called ngRepeat written in the AngularJS framework.

Why Learn React

As shown in Figure 2, this is how a directive is written in the AngularJS framework.

If one is not familiar with Ionic/Angular, this code snippet may raise some immediate questions of what is the $scope and what is the specific syntax here for the filter.

But in React, one can use the existing knowledge of language fundamentals. The above functionality can be done using filter and map functions in React. The following Figure 3 shows how to write the function in ReactJS.

As shown in Figure 3, functions can be written in easy ways compared to other frameworks. A few questions may also arise regarding what React. create class does and what render is but the rest of the code is regular JavaScript. This means it will be quite easy and understandable to those who do not even know much of React.

Advantages of ReactJS Development Services

React is Fast and Agile

ReactJS is featured with one-way unidirectional data flow between the states and lay-ers in an application. This means data flows in a single direction between the application states and layers. In two-way data binding like Angular, if a model is changed, the view also changes and vice-versa. React renders the updates in the DOM much quicker than alternative frameworks and it is a much smaller library. DOM means document object model. Thus, it is easy to choose the tools to get the job done.

React Introduced JSX

JSX is a language that lets you specify the DOM elements before the components right inside JavaScript files. This means the logic behind the components and the visuals are all in one place. This is such a great idea when other frameworks are taking queues to place them.

Big Development Community

Big companies like New York Times, Airbnb, Facebook, and Netflix are using React in production. They are continuously contributing to developing the React core and building amazing third-party libraries that work great with any Reactjs web application.
