Show usage of call, apply bind.

Function Composition and Chaining: `call` and `apply` can be used to chain and compose functions. By setting the context to the result of one function, you can chain another function call to operate on that context.

Method Borrowing: When you have a method defined on one object, but you want to use it on another object that doesn't have that method, you can use `call` or `apply` to borrow the method from the first object and execute it in the context of the second object.

Function with Varying Arguments: When a function can accept a variable number of arguments, you can use `apply` to pass an array-like object as arguments to the function.

Setting Context for Callbacks: When you pass a function as a callback to another function, the context can change. Using bind, we can ensure that the callback function maintains the desired context.

Using Functions as Constructors: In JavaScript, functions can be used as constructors to create objects. `call` and `apply` can be used to set the newly created object as the context while initializing properties.
