While I agree with making code editable in single lines as much as possible, I think this is a particularly bad example. I do prefer the comma first style for arrays and objects, but not for variable declarations. I used to use this exact style a couple years ago, but now I prefer to explicitly declare every variable with `var` to prevent any possible, syntactically correct, error that would result in a global variable.

It's even easier to create three separate var statements and let a JavaScript compressor handle it:

    var one = "foo";
    var two = "bar";
    var three = "baz";
