Answer 1

JavaScript is single-threaded. A function cannot be interrupted, so you can be sure each function block will complete before another begins.

(However, if a function makes an asynchronous call, other functions may execute before the asynchronous operation starts. That doesn't happen in your code, though, that I can see, besides the setTimeout calls, and you can be sure those will execute in the correct order.)
