Function make_local_variables

code2flow/javascript.py:174–200

Given an ast of all the lines in a function, generate a list of variables in that function. Variables are tokens and what they link to. In this case, what it links to is just a string. However, that is resolved later. Also return variables for the outer scope parent :param

(tree, parent)
