Bug 152320 – [JSC] TypedArray.prototype.slice() with no argument throws TypeError

• Status: RESOLVED
• Resolution: INVALID
• Component: JavaScriptCore

[Jinyoung Hur]

Below code throws TypeError saying, "Expected at least one argument".

var arr = new Uint8Array([1,2,3]);
arr.slice();

According to below reference, it seems that TypedArray.prototype.slice() should return [1,2,3] because, when omitted, begin is assumed to be zero and end is assumed to be array.length.

I realized that TypedArray.prototype.slice() is not implemented yet in WebKit.
I'm closing this bug.
