Question

Something like this works, but looks a bit clumsy:

for (i in {foo: 1, bar: 1, wah: 1}) {  // loops through foo, bar, wah
  console.log(i + " haha");            // can view using Firebug or Chrome 
}

if using an array, I don’t want to create any global temporary variable for the array… Also, this has to work in any modern browser IE7 / FF / Chrome / Safari. thanks.

Answer 1

You need to declare i for certain browsers.

I would use the initialization section of a for loop to declare the variables.

Array:

for (var i = 0, arr = ['foo', 'bar', 'wah']; i < arr.length; i++) {
  console.log(arr[i] + " haha");
}
