What are Components?

Component is an "ES6 Class" in react. It takes some input (most often props or properties) and then returns a React Element that describes how a section of UI should apprear on user screen or how this part should look like.

Types of Components

There are 2 kinds of component in React:

  • Class Components
  • Functional Components

Functional Components

Functional Component is easy to make, with minimum haslte. It has no complexity. There is no concept of state in a Functional Component.

Example of it will be:

function Home(props){
  return (

Class Component

Class component is more complex, it is mostly used in React and has the right to create and use "state" in React.

Example of it will be:

class Home extends Component{
  state = {
    name: "Peter Martin",
    age: 29,
    country: "USA"

        {/* has access to state */}
        {/* has also access to props object (passed from parent) */}
