Someone Halp!

Name: Anonymous 2010-11-10 2:20

What in the fuck:

Array.prototype.foldr = function(func, initial) {
    return this.reduce(function(sum, x) {
      return function(n) {
      return sum(func(n, x));
      };
    }, function(x){return x;})(initial);
}

That is retarded, you should write normal code like this:



Array.prototype.foldl = function(f,z){

for(i = 0; i < this.length; i++){

   z = f(z,this[i]);

}

return z;

}

Javascript sucks at tail recursion, so you better translate your snippet to imperative code. Also foldl is more natural in this context and has no disadvantage over foldr. If you want foldr, walk over the list reverse (start by (length - 1)).

you can't tell me what to do.

And you're silly implementation will not take advantage of the multicore javascript enabled future.

You'll be left behind in the dark ages of computing.

multicore javascript enabled future

folds cannot (in general) be parallelized.

javascript enabled apps of the future will inspect the properties of the operation in the fold, and paralyze as necessary in different iframes. This is done using the <hoist><isub parallel="true"/></hoist> combinator pop up menu jquery.

My Firefox doesn't like the sound of this.

With a supporting type system you can annotate the closure with the associative property. But no, you can't use analysis.

But that operation will yield a map then, so why not use map in the first place?
