sourceURL and usecases

[paulirish]

We do have docs here, but this might make sense for a focused blog post or SO answer.

docs: https://developer.chrome.com/devtools/docs/javascript-debugging#@sourceurl-and displayname in action

Use cases:

• assigning a source filename to
  • eval()
  • executeScript()
  • inline script tag
  • inline style tag

In many cases build systems or module loaders should be doing this.
