Is there a shorter way in JavaScript to trigger a function before and on resize? -


here example of mean.

function x() {     return ($(window).width() < 768) ? $('body').addclass('z') : $('body').removeclass('z') }  function y() {     x()      $(window).on('resize', function() {         x()     }) }

if don't invoke function before attached window resize event can manually invoke resize during attachment:

$(window).on('resize', x).trigger('resize');

but downside of approach not fire x function create fake resize event (it can problematic in scenarios).
