screen.width and screen.availwidth difference in javascript

Question

What is the difference between screen.width and screen.availwidth in JavaScript?

On my system both are the same!

Answer 1

• window.screen.width -> Returns the width of the screen.

• window.screen.availWidth -> Returns the amount of horizontal space in pixels available to the window.

It is best to use screen.availWidth for the exact size available for our component example.
