    array-sugar Build Status

    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.min([1, 3])        instead      Math.min.apply(null,[1, 3]);
         Array.max([1, 3])        instead      Math.max.apply(null,[1, 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.replace(o, n)      instead      array[array.indexOf(o)] = n;
         array.findOne(test)      instead      array.filter(test)[0];
         array.clear()            instead      array.length = 0
         array.copy()             instead      array.slice(0)
         array.unique()           instead      array.filter(function(function(itm,i,a){return i === a.indexOf(itm);}))
         array.unique.push(item)  instead      if (~self.indexOf(item)) { self.push(item); }
         array.unique.merge(arr)  instead      as previous but for all items in arr
         array.insert(i,item)     instead      array.splice(i, 0, item); //plus insert can take variable number of args, not just one
         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 with regular script tag) and you should be good to go.

    npm install array-sugar
    bower install array-sugar
    jspm install npm:array-sugar
    

    Then require('array-sugar'); and you're done.

    known incompatibilities

    Angular ngSanitize module in it's method assigns to arr.last and this collides with our 'last' getter.

    Is it a good idea to extend array.prototype?

    If I am writing a web app, NOT a library/framework, I don't consider this a bad practice. I have quite few libraries and I do not use array-sugar in them even if It would be helpful most of the time. Users of these libraries would have their Array unexpectedly extended and that is not a good practice. If you are building an end product used by end-user, I think it is quite allright to have these methods straight on array.prototype.
