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