esid: sec-arraybuffer.prototype.transfertofixedlength
description: Throws a TypeError if provided length cannot be coerced to a number
info: |
ArrayBuffer.prototype.transferToFixedLength ( [ newLength ] )
1. Let O be the this value.
2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]).
3. If IsSharedArrayBuffer(O) is true, throw a TypeError exception.
4. If IsDetachedBuffer(O) is true, throw a TypeError exception.
5. If newLength is undefined, let newByteLength be
O.[[ArrayBufferByteLength]].
6. Else, let newByteLength be ? ToIntegerOrInfinity(newLength).
