i'm a front end developer with 5 years of experiience, if this "callback" thing were actually useful i'd hvae heard of it by now

pls help, "myCallback" is the callback function i wrote and i'm calling it but it doesnt work the way its supposed to

$(function() {
  setTimeout(myCallback(), 1000);
});

but then how do i call it

ok i put the call after the timeout like you said but it's still happening too soon

$(function() {
  setTimeout(myCallback, 1000);
  myCallback();
});

i took the call out and moved it inside the callback function so that setTimeout will call the function

function myCallback() {
  myCallback();
  console.log("Ping!");
}

$(function() {
  setTimeout(myCallback, 1000);
});

now my page hangs! maybe there is a browser bug? (i am using firefox)

$(function() {
  setTimeout(function() {
    myCallback();
  }, 1000);
});

callback's are dumb
