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

As a matter of fact, I think using a object is a good idea.

var scope = {}
for (var i=1;i<=20;i++) {
  scope['a'+i] = 'stuff';   
}

The result will be you have a scope object that contain every newly create variable you want!
