It looks easy enough to polyfill.
Array.of = function(/* arguments */) {
return Array.prototype.slice.call(arguments);
};
from fantasy-land.
I wouldn't recommend that specific polyfill. In ES6 it's speced to be |this| sensitive and generic. It's more like:
Array.of = function of(){
var Ctor = typeof this === 'function' ? this : Array;
var out = new Ctor();
for (var i=0; i < arguments.length; i++) {
out[i] = arguments[i];
}
return out;
};
But yeah I was just commenting on the fact that the stock ES5 Array is not a complete implementation.
from fantasy-land.
ES6 has a a partial implementation of Monad.
ES5 has a complete implementation of Functor.
When Foldable is defined, ES5 hopefully has a complete implementation.
from fantasy-land.
@pufuwozu what is Foldable
? is it a correct implementation of reduce
.
from fantasy-land.
@Raynos: Foldable is implemented by providing a foldr
, or in JavaScript terms, reduceRight
.
