What is a method that can be used to increment letters?

Question

Does anyone know of a Javascript library (e.g. underscore, jQuery, MooTools, etc.) that offers a method of incrementing a letter?

I would like to be able to do somet

Answer 1

I needed to use sequences of letters multiple times and so I made this function based on this SO question. I hope this can help others.

function charLoop(from, to, callback)
{
    var i = from.charCodeAt(0);
    var to = to.charCodeAt(0);
    for(;i<=to;i++) callback(String.fromCharCode(i));
}

• from - start letter
• to - last letter
• callback(letter) - function to execute for each letter in the sequence

How to use it:

charLoop("A", "K", function(char) {
    //char is one letter of the sequence
});
