What is the vanilla ES6 equivalent of jQuery's $.when() for promises?

What is the non-jQuery equivalent of $.when() for regular promises? If there is one. If not, how might one implement it? I looked at the jQuery source to get an idea, and it seems manageable, but I'd rather not write it myself if there exists a standard implementation already.

Solution

  • Promise.all() is what you're seeking.

    Promise.all([
  promise1,
  promise2
]).then(/* do something */);
