Sproutcore vs Cappuccino speed

I am evaluating sproutcore and cappuccino for use in my current project. Since I am a rails developer and I like pure javascript I think that sproutcore suits my style better.

Javascript fastest way to duplicate an Array

In order to duplicate an Array in Javascript, does anyone know (and maybe tested) if it's faster to use: Slice method: var dup_array = original_array.slice(); or For loop: for(var i = 0, len = original_array.length; i < len; ++i) dup_array[i] = original_array[i]; UPDATE: (just to clarify myself) I know both ways do only a shallow copy : if original_array contains references to o

JavaScript最快的方式来复制一个数组

为了在JavaScript中复制数组, 有没有人知道(也许测试过)如果使用速度更快: 切片方法: var dup_array = original_array.slice(); 或For循环: for(var i = 0, len = original_array.length; i < len; ++i) dup_array[i] = original_array[i]; 更新:(只是为了澄清我自己)我知道这两种方法只做一个浅拷贝 :如果original_array包含对象的引用,对象将不会被克隆,但只有引用将被复制,因此两个数组都会引用相同
