javascript - new Promise(() = {}), if resolve or reject is not called, is it always in the pending state?

Question

new Promise(() => {}), if resolve or reject is not called, is it always in the pending state? {Code...} can have the effect of interrupting execution, but I don’t know if there are any disadvantages? I hope those who know more can give some advice~
