pub unsafe extern "C" fn JobQueueIsEmpty(cx: *mut JSContext)Expand description
Inform the runtime that the job queue is empty and the embedding is going to
execute its last promise job. The runtime may now choose to skip creating
promise jobs for asynchronous execution and instead continue execution
synchronously. More specifically, this optimization is used to skip the
standard job queuing behavior for await operations in async functions.
This function may be called before executing the last job in the job queue. When it was called, JobQueueMayNotBeEmpty must be called in order to restore the default job queuing behavior before the embedding enqueues its next job into the job queue.
