pub unsafe extern "C" fn UseInternalJobQueues(
    cx: *mut JSContext
) -> bool
Expand description

Use the runtime’s internal handling of job queues for Promise jobs.

Most embeddings, notably web browsers, will have their own task scheduling systems and need to integrate handling of Promise jobs into that, so they will want to manage job queues themselves. For basic embeddings such as the JS shell that don’t have an event loop of their own, it’s easier to have SpiderMonkey handle job queues internally.

Note that the embedding still has to trigger processing of job queues at right time(s), such as after evaluation of a script has run to completion.
