How do I set a specific order of execution when asynchronous calls are involved?

Question

I am new(2 days!!) to the world of JavaScript and my only prior coding experience is in Java where execution of statements takes place sequentially. I understand that or at

A lot of what you've said is wrong. JavaScript is sequential in the same way as Java, but asynchronous calls are made more often. If you want your callback to be called after the long thing, you must call it after the long running program. Like so -

console.log("Beginning");
function Test(callback){
   setTimeout(function(callback){
    console.log("Something that takes a lot of time");
    callback();
   },5000);

 }
function tstCallBack(){
   console.log("Should come last");
}
Test(tstCallBack);
