Replace With Alphabet Position

Welcome.



In this kata you are required to, given a string, replace every letter with its position in the alphabet.

If anything in the text isn't a letter, ignore it and don't return it.

"a" = 1, "b" = 2, etc.

Example



alphabetPosition("The sunset sets at twelve o' clock.")

Should return "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11" (as a string)

function wave(str){
let newArray = [];
let upperCaseIndex = 0;
let blankSpace = 0;
for(let x = 0; x < str.length; x++) {
waveArray.push(str);
}
for(let x = 0; x < waveArray.length; x++) {
let word = waveArray[x].split("");
let upperCaseLetter = word[upperCaseIndex].toUpperCase();
if(word[x] === " "){
upperCaseIndex++
} else {
upperCaseIndex++
word.splice(x,1,upperCaseLetter)
newArray.push(word.toString().replace(/,/g,''))
}
}
return newArray;
}
