A Web page can load a lot faster and feel faster if the Javascr ipt files referenced on the page can be loaded after the visible content has been loaded and multiple Javascr ipt files can be batched into one download. Browsers download one external Javascr ipt at a time and sometimes pause rendering while a scr ipt is being downloaded and executed. This makes Web pages load and render slowly when there are multiple external Javascr ipt references on the page. For every Javascr ipt reference, the browser stops downloading and processing of any other content on the page and some browsers (like Internet Explorer 6) pause rendering while it processes the Javascr ipt. This gives a slow loading experience and the Web page kind of gets stuck frequently. As a result, a Web page can only load fast when there are small number of external scr ipts on the page and the scr ipts are loaded after the visible content of the page has loaded.-A Web page can load a lot faster and feel faster if the Javascr ipt files referenced on the page can be loaded after the visible content has been loaded and multiple Javascr ipt files can be batched into one download.
