How can I loop through a set of strings in Javascript?

Question

I have a simple for loop that I need to set up. However instead of iterating through numbers I would like to iterate through:

"A", "B", "1" and then "2"

Is there a way I can do this with just creating an inline array?

you have to be more specific about the order, if it's just four things - what's the problem with creating an array? You have to specify what you're iterating through somewhere and unless there is a pattern, I don't see how you can avoid writing it down. — Benjamin Gruenbaum

Why is an array a problem? It could be as simple as ["A", "B", "1", "2"].forEach(...) — Yoshi

You could do Array.prototype.forEach.call('AB12', ...), but why? — Blender

As far as I understand, you would like to replace the usage of for() loop

var i;
var array = ["A", "B", "1", "2"];
for (i = 0; i < array.length; ++i) {
    alert(array[i]);
}

You can do that by simply using forEach() function

var array = ["A", "B", "1", "2"];
array.forEach(function(value) {
    alert(value);
});
