Example:
Download the package from here: https://github.com/Marak/faker.js
Then open the file "build/faker.js" (File is only 1.308 Kb in size, but contains 70655 lines!)
When I open that file, I get to enter a few characters, then auto completer kicks in and the editor locks up. (No crash. It just locks up and I have to manually cancel the task)
