// Make a quick copy and save the results in a real array: // First parameter sets the "this" value var newArray = Array.prototype.slice.call (anArrayLikeObj, 0); |
The slice() method returns a shallow copy of a portion of an array into a new array object selected from begin to end (end not included). The original array will not be modified.
