anonymous setTimeout function

i have a situation where i am waiting for a couple of events to happen. i see many good examples of how to use the setTimeout using a named function, but is there a way to use some sort of anonymous method for a timeout?

the code currently looks something like this:

testForObject();

function testForObject() {
    if  ( typeof marksObjectName === 'object' )  {
           // blah blah
    } else {
       console.log('marksObjectName does not exist quite yet');
       setTimeout(function() { testForObject() }, 500 );
    }
}

so i was wondering if there is some way naming the function during setTimeout and use an anonymous method instead, perhaps something like this:

setTimeout(function() {
    if  ( typeof marksObjectName === 'object' )  {
           // blah blah
    } else {
       console.log('marksObjectName does not exist quite yet');
    }
}, 500);

obviously this does not work, but it was my first (and only) guess.

thank you all very much.

You can name the function as follows. Note that you will need to put it within another timeout within the else clause:

setTimeout(function timer() {
  if (typeof marksObjectName === 'object') {
    // blah blah
  } else {
    console.log('marksObjectName does not exist quite yet');
    setTimeout(timer, 500);
  }
}, 500);

You can name the passed function, like

setTimeout(function myFunction() {
    // ...
}, 500);

I believe hat setInterval is what you are looking for.

setInterval(function() { if ( typeof marksObjectName === 'object' ) { // blah blah } else { console.log('marksObjectName does not exist quite yet'); } }, 500);
