Bootloader is an important part of Facebook's front-end code, which allows Javascript libraries to be lazy-loaded as needed instead of on page load. A couple of Facebook developers go into further detail here if you'd like to know more.

You can use RequireJS, LABjs or others to achieve the same thing.
