TypedArray.prototype.slice()

The slice() method of TypedArray instances returns a copy of a portion of a typed array into a new typed array object selected from start to end (end not included) where start and end represent the index of items in that typed array. The original typed array will not be modified. This method has the same algorithm as Array.prototype.slice().
