Do Something if Screen if Smaller than in jQuery

How to run a jQuery function when screen is smaller than a certain breakpoint using window width.

Last week i wanted to do some jQuery functions when the screen was smaller than a certain size. This script will help you run your functions when reaching a certain break point. 

if ($(window).width() < 767) {
   alert('Less than 767');
}
else {
   alert('More than 767');
}
