What Is React Development

React is a JavaScript-based UI development library. Facebook and an open-source developer community run it. Although React is a library rather than a language, it is widely used in web development. The library first appeared in May 2013 and is now one of the most commonly used front-end libraries for web development.

Why React?

React’s popularity today has eclipsed that of all other front-end development frameworks. Here is why:

  1) Easy creation of dynamic applications: React makes it easier to create dynamic web applications because it requires less coding and offers more functionality, as opposed to JavaScript, where coding often gets complex very quickly.

  2) Improved performance: React uses Virtual DOM, thereby creating web applications faster. Virtual DOM compares the components’ previous states and updates only the items in the Real DOM that were changed, instead of updating all of the components again, as conventional web applications do.

 3) Reusable components: Components are the building blocks of any React application, and a single app usually consists of multiple components. These components have their logic and controls, and they can be reused throughout the application, which in turn dramatically reduces the application’s development time.

Features of React

React offers some outstanding features that make it the most widely adopted library for front-end app development. Here is the list of those salient features.

  1) JSX:- JSX is a JavaScript syntactic extension. It’s a term used in React to describe how the user interface should seem. You can write HTML structures in the same file as JavaScript code by utilizing JSX.

  2) Virtual Document Object Model (DOM):- The Virtual DOM is React’s lightweight version of the Real DOM. Real DOM manipulation is substantially slower than virtual DOM manipulation. When an object’s state changes, Virtual DOM updates only that object in the real DOM rather than all of them.

  3) Architecture:- MVC is an architectural pattern that splits the application layer into Model, View, and Controller. The model relates to all data-related logic; the view is used for the UI logic of the application, and the controller is an interface between the Model and View.

 4) Extensions:- React goes beyond just being a UI framework; it contains many extensions that cover the entire application architecture. It helps the building of mobile apps and provides server-side rendering. Flux and Redux, among other things, can extend React.

  5) Data Binding:- Since React employs one-way data binding, all activities stay modular and quick. Moreover, the unidirectional data flow means that it’s common to nest child components within parent components when developing a React project.

 6) Debugging:- Since a broad developer community exists, React applications are straightforward and easy to test. Facebook provides a browser extension that simplifies and expedites React debugging.

Components in React

Components are the building blocks that comprise a React application representing a part of the user interface.

React separates the user interface into numerous components, making debugging more accessible, and each component has its own set of properties and functions.

Here are some of the features of the Components -

 1) Re-usability - A component used in one area of the application can be reused in another area. This helps speed up the development process.

  2) Nested Components - A component can contain several other components.

  3) Render method - In its minimal form, a component must define a render method that specifies how the component renders to the DOM.

 4) Passing properties - A component can also receive props. These are properties passed by its parent to specify values.
