Answer 1

are variables declared and assigned in an "if" statement visible only within that "if" block or within the whole function?

In Javascript, all variables are either

• global scope
• local scope (entire function) - Javascript doesn't have a "block scope" where variables are only available with a smaller block of the local scope (function)

am i doing this right in the following code? (seems to work, but declaring "var structure" multiple times seems akward) any cleaner solutions?

Yes. A cleaner solution might be to build a base class of structure, and modify what is different in each case.
