How Do React Components Aid in Web Application Development?

A React component is one of the core elements of React application. In other words, any application you create in React will be built using elements known as React components. The react js development company developer can build the UI faster using React components.

React components are of two types:

Functional Components
Class Components

In addition to these two components, React contains other similar elements that aid in developing the application.

Let’s move on to the different components of ReactJS.

Components of ReactJS

Functional Components
Functional components are JavaScript functions that help in creating React applications. The functional components are helpful whenever the functional component does not require the data from any other components. Meaning, functional components do not interact with other components.

Class Components
Class components are similar to functional components. But class components are more complex than functional components. Class components interact with each other. Therefore, class components exchange data with other components.

Higher-Order Components
The Higher-Order Components (HOC) accept a component as input and return the component as output, but with additional functionality. HOC in React is a standard advanced React paradigm for deploying reusable logic and functionality across React components.

Dumb Components
Dumb components are also known as stateless functional components since it requires only a few computer resources to render such as memory, CPU, and GPU.

Smart Components
Any class component that maintains its state is also known as a smart component. Smart components work similarly to class components. When we work with Babel or ES6-style React, we know it as any class object that extends components.

Presentational Components
The presentation component is also known as a stateless functional component that takes props and renders UI. Plain JavaScript functions that do not have states are also known as stateless functions. Presentational components are the components that receive state from the higher-order component. UI is conditionally rendered based on state, which is provided to them as a parameter. The presentational component is mainly concerned with how things are displayed more than the management of the state.

Container Components
A container component is a type of class component that delivers data and behavior to other container components. In addition to that, the container retrieves data and then produces the relevant sub-component. Thus, container components focus on working conditions.

What is React Native?
React Native (RN) is an open-source framework that helps to develop mobile applications using reusable components. Similarly, React Native produces applications using JavaScript. After, creating the React Native codes, the developer can use the code both on Android and iOS. Thus, it provides a massive transformation of code within less time.

Facebook built React Native for an internal project named Hackathon in 2013. In addition to that, React Native was made open and accessible on GitHub by Facebook in March 2015.
