Understanding How State work in ReactJS
What is State in ReactJS?
A plain JavaScript object used by React to represent information about the component’s current situation is called the state in ReactJS.
It is just like any other function in a component. The only difference being that a normal variable disappears as the function exits, but React preserves the state variables.
How to Create a State Object?
class Car extends React.Component {
constructor(props) {
super(props);
this.state = {brand: "Ford"};
}
render() {
return (
<h1>My Car</h1>
);
}
}
