To return the live width of the current window in Javascript, use a property of the window that is innerWidth.
Step: 1 Write HTML documentation and use a script tag to code in Javascript.
Step: 2 Pass onresize event on the window. Now, the code in the onresize event function will execute as many times as the window resizes.
Step: 3 You can use any Javascript selector to print the result in. Here I am directly printing the result in the body. So, I have selected the body like this document.body
Step: 4 Use innerHTML output property to print the result in the selected DOM (Document Object Modal).
Step: 5 For window width, use the innerWidth property to return the current width of the window.
