ReactJS Tutorial
Understanding ReactJs useState Hook
What is useState Hook in ReactJS?
We know that there are two types of components in React: class and function.
In class, we initialize the count state to 0 by setting this.state to 0 in the constructor.
class Example extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0
};
}
What does useState return?
As discussed earlier, useState returns a pair of values: the current state and a function that updates it.
