setTimeout(myFunction, 5000); vs setTimeout(myFunction(), 5000);

Question

I was playing around with the \"setTimeout\" function. This code runs like expected:

function myFunction() {
    console.log(\'test\');
    setTimeout(myFunction         


        

Answer 1

myFunction() calls the function immediately and passes its return value to setTimeout to be called later (except its return value is undefined, which isn't a function (or a string), so that is pointless).
