//
// What is an anagram ? Well, two words are anagrams of each other if they both contain the same letters.For example:

// 'abba' & 'baab' == true
// 'abba' & 'bbaa' == true
// 'abba' & 'abbba' == false
// 'abba' & 'abca' == false

// Write a function that will find all the anagrams of a word from a list. You will be given two inputs a word and an array with words. You should return an array of all the anagrams or an empty array if there are none. For example:

// anagrams('abba', ['aabb', 'abcd', 'bbaa', 'dada']) => ['aabb', 'bbaa']
// anagrams('racer', ['crazer', 'carer', 'racar', 'caers', 'racer']) => ['carer', 'racer']
// anagrams('laser', ['lazing', 'lazy',  'lacer']) => []

function anagrams(word, words) {
    wArr = word.split("").sort((a, b) => (a < b ? -1 : 1));
    let result = [];
    word = word.split("").sort((a, b) => a.localeCompare(b)).join("")
        
    for (let w of words) {
        if (word == w.split("").sort((a, b) => a.localeCompare(b)).join(""))
            result.push(w);
    }

    return result;
}

anagrams("abba", ["aabb", "abcd", "bbaa", "dada"]);
//=> ['aabb', 'bbaa']

anagrams("racer", ["crazer", "carer", "racar", "caers", "racer"]);
//=> ['carer', 'racer']

anagrams("laser", ["lazing", "lazy", "lacer"]);
//=> []
