Convert number to alphabet letter

Question

I want to convert a number to its corresponding alphabet letter. For example:

1 = A
2 = B
3 = C

Can this be done in javascript without manually creating the array? In php there is a range() function that creates the array automatically. Anything similar in javascript?

Answer 1

Yes, with Number#toString(36) and an adjustment.

var value = 10;

document.write((value + 9).toString(36).toUpperCase());

Answer 2

Snippet below turns the characters in the alphabet to work like numerical system

1 = A
2 = B
...
26 = Z
27 = AA
28 = AB
...
78 = BZ
79 = CA
80 = CB

var alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
var result = ""
function printToLetter(number){
    var charIndex = number % alphabet.length
    var quotient = number/alphabet.length
    if(charIndex-1 == -1){
        charIndex = alphabet.length
        quotient--;
    }
    result =  alphabet.charAt(charIndex-1) + result;
    if(quotient>=1){
        printToLetter(parseInt(quotient));
    }else{
        console.log(result)
        result = ""
    }
}

I created this function to save characters when printing but had to scrap it since I don't want to handle improper words that may eventually form
