React for Angular Developers

Introduction

React is a Javascript library unlike Angular - which is a framework.

• - React has only components

• - React has a virtual DOM object for every DOM object ; Limits frequently updating the DOM

• - Only one element rendered per component : JSX

Components

React contains only two types of components: Functional and Class based .

Functional components are stateless and have no constructor

function App() {
    return (
        
Hello, World
	
    );
}
export default App;

Class-based components are stateful i.e they keep track of changing data

class HasTheParameter extends React.component{
    render(){
        return (
{this.props.theParameter}
)
    }
}
export default HasTheParameter;
