Code quality.

README.md

This is an excerpt from a 465 lines js file. This is not satirical. This is actual code from a large codebase (>100k js) of an application that is used in production at multiple customers.

If you're giving a talk or lecture about code quality, feel free to use this as the first slide to make your audience giggle for a second. And then look at their faces when you tell them it's actual code.
