array-sugar
Advanced tools
adds last, first, remove, contains, isEmpty and empty to array utilizing Object.defineProperty
Tired of not having a last property on array in Javascript? Tired of not having contains method? This little script solves those by adding a bit of sugar allowing you to do:
Array.range(1,3) instead [1, 2, 3];
array.contains(o) instead array.indexOf(o) != -1
array.remove(o) instead array.splice(array.indexOf(o), 1) //remove returns true when o was removed
array.clear() instead array.length = 0
array.copy() instead array.slice(0)
array.insert(i,item) instead array.splice(i, 0, item); //plus it can take variable number of args
array.isEmpty instead array.length == 0
array.first instead array[0]
array.last instead array[array.length-1]
Usable in any environment that supports Object.defineProperty(oldest would probably be IE9).
Available through npm and bower, just require(or include in index.html) and you should be good to go.
npm install array-sugar
bower install array-sugar
Tests via nodeunit included.
#known incompatibilities Angular ngSanitize module in version 1.2.0-rc2 in it's method assigns to arr.last and this collides with our 'last' getter. So beware, I have created a pull request so that ngSanitize doesn't break, but who knows when it is going to be merged. For now, use ngSanitize from my fork: compatible ngSanitize
Missing any sugar? Please do submit a pull or feature request.
