Once there was a little website
that traveled at the speed of light
but what we cannot see,
Http server requests via TCP
the parsed out info came to the client, quite right.
Basically what ends up happening is the website needs a higherarchy in regards of what to read first. The HTML gets called first since it is the frame work but also it contains within the call to CSS, then when the call is answered it presents the parsed CSS and at the same time when the JavaScript is called it is answered with the parsed JavaScript.

Variable is legion. You can make just about anything a variable and then define it with a value that the user also gets to assign. They make up a lot of what goes on in JavaScript. If JavaScript was a machine variables could potentially be cogs, gears, leavers, screws, pedals, ball bearings, anything!
