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

To execute a function immediately
To create a new function with a fixed this value
The bind() method serves several crucial purposes: 1) Creates a new function with a fixed this context, 2) Allows explicit setting of the this value regardless of how the function is called, 3) Preserves the original function while creating a bound version, 4) Useful for maintaining context in callbacks and event handlers, 5) Can partially apply arguments creating partial functions, 6) Essential for ensuring proper object method context in event listeners.
To combine two functions together
To remove event listeners
