Keeping the global namespace clean with $script loader.

My latest side project requires that I put together a script to be consumed by third parties. This is similar to the scripts you need to import when using Google Analytics or Disqus in your site.

The most important thing when working in these types of scripts
is to keep the global space clean.

The problem

I wanted to use a script loader that allow for asynchronous loading of my dependencies.

After looking around in the web to some of the usual suspects I decided to try $script this time but I wanted to internalize it into my own code.

The script creates a $script global function that you use to import the scripts, check for ready status and a few more things.

The solution

I was ready to start reading and making changes to the code to create the function inside my own object instead of the global context when I noticed that the function that creates the object takes a third parameter named context.

Sure enough, passing a variable as the context (in my case the literal I use as a namespace) and the $script function is created on it while keeping the global context unmodified.

I really like when things are this easy. Big kudos to the authors of the library.
