  1. For some unknown reason my javascript code is not working/running in the browser. I am making a simple quoting generator with html & javascript, but it wont run in the browser. Can you please help me?

  2. I using a new(er) version of NotePad++, and if I type in what he did and did exactly that, it shows up as "var x = 32; document.write (x)" like that's exactly how it shows up. Maybe because the newer versions have a different way of doing it? I don't know. If anyone could help me with that, I'd appreciate that very much. Thnx!

  4. Does Javascript have variables? No. 

    Variables only exist in computer languages that assign actual memory addresses.

    Javascript has names. Names are tags to objects within the Javascript Virtual Computer  (JVC). Names are handles to JVC objects.

    The JVC has things inside called objects, which it lets us use to represent our concepts. JVC objects have fields of data with associated names. The data can be of two kinds, attribute data, and code data.

    Attribute data describe the current state of something. Code data tells the JVC to do action when commanded to do so.
