A look at different ways to dynamically load JavaScript files after the page is fully loaded

Dynamic loading of JavaScript files is one of the very useful tools that you must have in your set. It allows you to optimize web page performance by moving blocking scripts off the loading process (usually they call this “lazy loading”), and to load scripts only when the user needs them (usually they call this “on-demand loading”.) This tool will greatly improve your page performance if you use it wisely.
