Differences between Lodash and Underscore.js [closed]

Answer 1

I just found one difference that ended up being important for me. The non-Underscore.js-compatible version of Lodash's _.extend() does not copy over class-level-defined properties or methods.

I've created a Jasmine test in CoffeeScript that demonstrates this:

Fortunately, lodash.underscore.js preserves Underscore.js's behaviour of copying everything, which for my situation was the desired behaviour.
