bind(), call(), and apply()

class Component {
  constructor() {
    this.handleClick = this.handleClick.bind(this);
  }
  
  handleClick() {
    console.log(this.props);
  }
}

To create new methods
To ensure correct this binding in event handlers
bind() in constructors serves important purposes: 1) Ensures event handlers maintain class instance context, 2) Prevents this binding issues in callbacks, 3) Creates a stable reference that can be used for event listener removal, 4) Common pattern in React class components, 5) Alternative to arrow functions in class fields, 6) Binds once at initialization rather than on each render.
To prevent method overriding
