| [[Prototype]] defaults to %ArrayBufferPrototype% if NewTarget.prototype is not an object. |
| info: | |
| ArrayBuffer( length ) |
| |
| ArrayBuffer called with argument length performs the following steps: |
| |
| ... |
| 6. Return AllocateArrayBuffer(NewTarget, byteLength). |
| |
| AllocateArrayBuffer( constructor, byteLength ) |
| 1. Let obj be OrdinaryCreateFromConstructor(constructor, "%ArrayBufferPrototype%", |
| «[[ArrayBufferData]], [[ArrayBufferByteLength]]» ). |
| 2. ReturnIfAbrupt(obj). |
| ... |
