| [[Prototype]] defaults to %SharedArrayBufferPrototype% if NewTarget.prototype is not an object. |
| info: | |
| SharedArrayBuffer( length ) |
| |
| SharedArrayBuffer called with argument length performs the following steps: |
| |
| ... |
| 3. Return AllocateSharedArrayBuffer(NewTarget, byteLength). |
| |
| AllocateSharedArrayBuffer( constructor, byteLength ) |
| 1. Let obj be ? OrdinaryCreateFromConstructor(constructor, "%SharedArrayBufferPrototype%", |
| «[[ArrayBufferData]], [[ArrayBufferByteLength]]» ). |
| ... |
