Anqular: how does the framework parse dependencies?

Question

JavaScript

How does Angular detect dependencies based on a function signature of the form function($service1, $service2,...)?
Does the kernel parse the function's source code and extract the argument names from it?

Answer 2

Recursive overloading (or searching for a "leaf in a tree") is quite possible.
Perhaps it also initially checks that all input variables do not contain undefined.
Exact option: look at the source and understand the logic)

Yes

var foo = function($service1, $service2){}
foo.toString().match(/^[^\(]*\((.*)\)/)[1].split(',')
["$service1", " $service2"]
