Answer 1

You can use substr

for example:

new Date().getFullYear().toString().substr(-2)

Answer 2

you can also quote string

''+document.location+''.substring(2,3);

Answer 3

try this code below :

var currentLocation = document.location;
muzLoc = String(currentLocation).substring(0,45);
prodLoc = String(currentLocation).substring(0,48); 
techLoc = String(currentLocation).substring(0,47);

Answer 4

document.location is an object, not a string. It returns (by default) the full path, but it actually holds more info than that.

Shortcut for solution: document.location.toString().substring(2,3);

Or use document.location.href or window.location.href
