Javascript String Question 13

Introduction

Create a function that returns a string with the letters in alphabetical order (i.e. hello = ehllo).

Numbers, spaces and punctuation symbols should not be included in the string. 

function alphabetSoup(str) { 
    //your code/* w  w  w  .j  ava2 s .  co m*/
}

// Output
console.log(alphabetSoup("qwertyuiopasdfghjklzxcvbnm"));
// => "abcdefghijklmnopqrstuvwxyz"

console.log(alphabetSoup("Grumpy wizards make toxic brew for the evil Queen and Jack"));
// => "aaaabccddeeeeeefghiiijkklmmnnoopqrrrrsttuuvwwxyz"




function alphabetSoup(str) { 
    return str = str.toLowerCase()
                    .replace(/[^a-z]/g, "")
                    .split('')
                    .sort()
                    .join('');
}

// Output
console.log(alphabetSoup("qwertyuiopasdfghjklzxcvbnm"));
// => "abcdefghijklmnopqrstuvwxyz"

console.log(alphabetSoup("Grumpy wizards make toxic brew for the evil Queen and Jack"));
// => "aaaabccddeeeeeefghiiijkklmmnnoopqrrrrsttuuvwwxyz"

Notes

.replace(/[^a-z]/g, "") - Replace anything that is not an alphabetic character with an empty string.
