Loading scripts asynchronously will improve page speed and make the website load much faster.
Here are some key features of "NBL.js":
· Trigger a callback on a user definable timeout period
· Uses HTML5's data attribute for configuration, so load all scripts with one script-tag
· Load scripts asynchronously or in order, or any combination of both
· Every script can have its own callback
· Also available as a single line for inclusion in your HTML page
· Tested in Safari, Chrome, Firefox, IE6+, basically doing nothing too fancy.
· Less than 1kb
Requirements:
· JavaScript enabled on client side
