Using JavaScript to test if Beaver Builder Page Editor is active on a page or layout. This is useful if you to run a JavaScript Code on live page and not run it inside the Page Builder Editor --- or vice-versa, of course. :-)

bb-page-builder-check.js

jQuery(document).ready(function($){
	if( typeof window.FLBuilderConfig === 'undefined' || window.FLBuilderConfig === null ) {
		 // You are on a live page!
                // Rest of the code here; 
	}
});
