Script Execution flow in Javascript

Question

$(function() {
 alert("hello World");
});
alert("hello");

Output:

first "hello" is alert /which is on line 2/ then "hello world" alerted I want to know what is the execution rule in javascript

• dandavis: JS is event-driven, so flow coincides with the outside triggering of pre-defined events.

Answer 1

This block will execute when dom is ready.

$(function() {
 alert("hello World");
});

This is similar to

$(document).ready(function(){
});

And 2nd alert doesn't wait for the dom ready.

that's why 2nd alert executes first.
