Why is setTimeout executing immediately? [duplicate]

Answer 1

In your example you call function and its result is passed to the setTimeout function.

Valid way to use function stored in variable here is to do:

setTimeout(timeup, 10000);

But it disallows passing parameters. To pass parameters, you can try with:

setTimeout(function(){
  timeup(tc,chosen);
}, 10000);

Answer 2

You need to wrap your code in an anonymous function:

setTimeout(function() {timeup(tc,chosen)},10000);

This puts your code in context of the timer, as opposed to inline execution, which you are now seeing.

Answer 3

The point is you are calling the function previous to the timeout, when you add (tc, chosen) this fire the time up function.

Remove the ()

setTimeout(timeup,10000)

This will fire you function after 10000ms

Answer 4

because you're actually calling the timeup(tc,chosen) function inside the setTimeout function.

try:

setTimeout(function(){
  timeup(tc,chosen);
}, 10000);
