refactored to scope as much as possible. Wrapped entire script in an IIFE to scope functions & variables away from the window object. Should improve performance.
By using
var calcHtmlLink = function() {}instead offunction calcHtmlLink() {}, the function isn't created until it is needed, and can cleanup afterwords. Not only that, it is removed from global scope which when saturated degrades performance.Wrapped the entire function in a (function() {})() for the same reason.
Also went ahead and made all if/else statements use curly braces. I am all for the shorthand, but for best compatibility, we should wrap them.
added
varto some variables. When not declaring var, the js interpreter will elevate/hoist that variable to global scope. It does this as a way to ensure that the program will not crash.
