Only perform actions after window has finished resizing

resize.js

/*
    By default, $(window).resize() will fire every time the window is resized, so for each pixel it moves, it's called.
    This isn't necessarily always needed and some things can be left to when the window has finished resizing.
    We don't have a (native) way of doing this, but with this little snippet you can achieve basically what we want.
*/
var windowResize;
$(window).resize(function() {
    // Clear the timeout each time the window is resized
    clearTimeout(windowResize);
    
    // Start the timeout - after 500ms if the window hasn't been resized again it'll call our finishedResizing() function
    windowResize = setTimeout(finishedResizing, 500);
});
 
function finishedResizing() {
    // here we can do things that we want to do after the window has finished resizing.
