When the callbacks of then, catch, or finally are ready to be executed, where do they run?
I recently read on Stack Overflow that these callbacks are executed in the call stack of the main JS thread (due to JavaScript being single threaded).
If this is accurate, does it imply that these callbacks keep running until the call stack is clear?
Furthermore, is the same true for async-await?
According to popular belief, these callbacks are carried out within the call stack of the primary JS thread.
Affirmative.
Therefore, does this signify that these callbacks are not processed until the call stack is clear?
Indeed, similar to any other asynchronous callback, they must wait for the call stack to empty, and a lengthy script will hinder their execution.
Is the same true for async-await operations?
Yes.
