@CMS No, it's not really simple. It's really simple in every other language. It's ridiculously complex in JS, where you have in and of that can both be used and do different things. Then you also have forEach and the ugly and annoying index based looping. Every other modern language makes looping over a collection easy and straightforward with no surprises or confusion. JS could, too, but it doesn't.

Also : myStringArray.forEach(function(value, index){ console.log(index, value) }); and result will be 0 "Hello" 1 "World"

no, it's really simple, array objects have numeric indexes, so you want to iterate over those indexes in the numeric order, a sequential loop ensures that, the enhanced for-in loop enumerates object properties, without an specific order, and it also enumerates inherited properties... for iterating over arrays sequential loops are always recommended...

| Jun 10, 2010 at 0:15 | comment | added | Mark Szymanski | Ok, so I'm a bit confused, it's ok to use the enhanced for loop when you are accessing the objects? And use a sequential one for filling one? Is this correct? | |
