How To Run Sequence Functions In Javascript

How to run sequence functions in JavaScript: I've 4 functions like this: function myfunction() { callfunction1(); callfunction2(); } In callfunction1: function callfunction1

Solution 1:

JavaScript is single-threaded, callfunction2 will only run after callfunction3 has compeletely finished.

However, if callfunction3 contains some AJAX or other asynchronous operation, then that will always happen after callfunction2 (because of the single-threaded thing, it can't start the asynchronous callback until after the synchronous stuff is done). Anything that relies on the result of an asynchronous function MUST either be in the function itself, or called by said function.
