inject and collect with jQuery
You know, I would have thought someone had already made an enumerable plugin for jQuery. Maybe someone has. Mine is better.
- Complete coverage with screw-unit
- Interface so consistent with jQuery you’ll think it was core
1 2 3 4 |
squares = $([1,2,3]).collect(function () { return this * this; }); squares // => [1, 4, 9] |
It’s on github. It deliberately doesn’t have the kitchen sink – fork and add methods you need, there’s enough code it should be obvious the correct way to do it.
As an aside, it’s really hard to spec these methods concisely. I consulted the rubyspec project and it turns out they had trouble as well, check out this all encompassing spec for inject: “Enumerable#inject: inject with argument takes a block with an accumulator (with argument as initial value) and the current element. Value of block becomes new accumulator”. Bit of a mouthful eh.
Post your improvements in the comments.
