replace-with-alphabet-position.js

// 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 )

//solution
let alphabet = {
    a : 1, b : 2, c : 3, d : 4, e : 5, f : 6, g : 7, h : 8, i : 9, j : 10, k : 11, l : 12, m : 13, n : 14, o : 15, p : 16, q : 17, r : 18, s: 19, t : 20, u : 21, v : 22, w : 23, x : 24, y : 25, z : 26
}

function alphabetPosition(text) {
    return text.split("").filter(element => element.toUpperCase() != element.toLowerCase()).map(element => element.toLowerCase()).map(element => alphabet[element]).join(" ")

  }
