description: Return value from [[ArrayBufferByteLength]] internal slot
info: |
  24.1.4.1 get ArrayBuffer.prototype.maxByteLength

  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, return +0𝔽.
  5. If IsResizableArrayBuffer(O) is true, then
     [...]
  6. Else,
     a. Let length be O.[[ArrayBufferByteLength]].
  7. Return 𝔽(length).
