chrome debugger promises dont resolve while paused?

问题

Maybe I'm not debugging promises right but basically if you stop at break point and run async code it doesnt actually finishes until you resume execution and that's a problem. Debugger allows you to quickly experiment with multiple api methods... but you cant if you resume it

debugger;
//now type the following in console
Promise.resolve().then(()=> console.log('done'));

回答1:

It doesn't execute because the function in .then is only called when the current "thread" is finished. This is the same for all asynchronous calls such as setTimeout.
