Is the javascript linear loaded?

Question

I mean, if the first functions declared are the first functions loaded?

Because, if so, I could add a var loaded = true to the end of the file to know if it is loaded (I know I can use onload, but I would like this alternative also).

Answer 1

A lot depends on the browser you are using. Depending on your requirements, you might benefit from a script loader. That way you could declaratively define what scripts you wanted to load, and the loader would ensure that they are loaded once. Also, here is a little more information about javascript loading.
