How to contribute to Underscore.js
Before you open a ticket or send a pull request, search for previous discussions about the same feature or issue. Add to the earlier ticket if you find one.
If you're proposing a new feature, make sure it isn't already implemented in Underscore-Contrib.
Before sending a pull request for a feature, be sure to have tests.
Use the same coding style as the rest of the codebase.
In your pull request, do not add documentation or re-build the minified
underscore-min.jsfile. We'll do those things before cutting a new release.
