JavaScript setTimeout() in Chrome console - Stack Overflow

Why setTimeout doesn't work from Chrome console on some pages or what am I doing wrong?

setTimeout(function(){console.log('a');},3000);

output:

<- 6425

EDIT: Seems that on some pages console.log() is being overridden ... as it's site specific problem, this question should be deleted. But can't do that, as it has answers.

• 5 The number 6425 is the timeout id. So clearly it is at least creating the timeout. In 3 seconds, it should call the function. So why would it not show the log? Well is your console filtered to not show log lines? – epascarello Commented Oct 16, 2017 at 19:26
• 2 LOL.... it works.... – epascarello Commented Oct 16, 2017 at 19:27
• 2 No it outputs "a" after 3 seconds. – epascarello Commented Oct 16, 2017 at 19:28

It does work. The catch is you may not be waiting enough.

console.log(setTimeout(() => console.log('a'), 1000));

That number you get is the timeoutId. Anytime you call setTimeout or setInterval it returns a numeric ID which you can then pass to clearTimeout() or clearInterval() to abort it before it runs.
