Hey Mahesh👋🏻, You are 💯right. If we see the most features of famous Javascript frameworks are built upon these callback functions. We can't even imagine how Javascript world🌎 will look without callback functions.
I am glad that you liked♥ it. It motivates me😃 and more to come💪🏻.

Callback comes super handy if you want to create a dynamic form that automatically calculates the total from the previous inputs without even a click of button. It's great that you shared about this valuable knowledge. Thanks dude.
