LABjs :: Loading And Blocking JavaScript

by 2 others
LABjs (Loading And Blocking JavaScript) is an open-source (MIT license) project. on-demand JavaScript loader, capable of loading any JavaScript resource, from any location, into any page, at any time. LABjs by default will load (and execute) all scripts in parallel as fast as the browser will allow.
