This ensures the function only runs once regardless as to how many times the resize event has been fired. In these times, I use a script I like to call “Resize Intent.” The basic premise is to only run a desired fucntion once a user has finished resizing their browser, when they have resized the browser to the extent they intended.

Firing a function for potentially every pixel the browser changes can slow down certain browsers and cause them to function unpredictably and less smoothly. But a node can have only one onclick attribute, so you can register only one. At times, the function(s) you wish to tie to the browser resize event can be cumbersome and expensive, which means it takes time to run. Calling its addEventListener method registers the second argument to be.

When resizing, your browser’s JavaScript resize event fires for potentially every pixel the browser resizes. There are often functions we wish to perform on our sites when a user resizes the browser.
