Declare variables programmatically?

Question

I am trying to create a bunch of variables like this:

function l(){
    var a1 = 2,
        a2 = 4,
        a3 = 6,
        a4 = 8,
          .
          .
          


        

Answer 1

Don't do this. Do. Not. Do. This. Use an array.

Given the trouble you're having creating them programmatically, how do you think you'd refer to them programmatically?
