| get SharedArrayBuffer.prototype.growable |
| |
| 1. Let O be the this value. |
| 2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]). |
| 3. If IsSharedArrayBuffer(O) is false, throw a TypeError exception. |
| 4. Return IsResizableArrayBuffer(O). |
| |
| IsResizableArrayBuffer ( arrayBuffer ) |
| |
| 1. Assert: Type(arrayBuffer) is Object and arrayBuffer has an |
| [[ArrayBufferData]] internal slot. |
| 2. If buffer has an [[ArrayBufferMaxByteLength]] internal slot, return true. |
| 3. Return false. |
