TypedArrayを使っているときに、これあったら便利だよね的なメソッド(本当はこういうことはやらないほうがいいんだけど)。 (function(){ function TypedArrayMixin(){ this.forEach = function(callback){ for(var i = 0, n = this.length; i < n; ++i) callback(this[i], i); }; this.map = function(callback, context){ var ret = new this.constructor(this.length), i, n; for(i = 0, n = this.length; i < n; ++i) ret[i] = callback.call(context, this[i], i); return ret; };
