if i fire up 2 functions like this:

prepare_data();

read_data();

then i guess they are running at the same time. but as you can see function two is depending on the first one, so how can i make the latter one run after the first one is completed?

Javascript, and most other languages, run code sequentially.

Therefore, they will not both run at the same time.

In fact, it is not possible to run two different pieces of Javascript code at the same time. However, in many other languages, it is possible using threads.

However, if they make AJAX calls, the corresponding server-side code called by both functions will run simultaneously.

To prevent that, you'll need to make the first function accept a callback parameter and pass it the second function.
