What is the usage of Function.prototype.bind?

The bind method returns a new function that is bound to a specific this value or the "owner" object, So we can use it later in our code. The call, apply methods invokes the function immediately instead of returning a new function like the bind method.

import React from 'react';
class MyComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
value: '',
};
// Binds the "handleChange" method to the "MyComponent" component
this.handleChange = this.handleChange.bind(this);
}
handleChange(e) {
//do something amazing here
}
render() {
return (
<>
<input type={this.props.type} value={this.state.value} onChange={this.handleChange} />
</>
);
}
}
