A method to sort an array of strings so that all the anagrams next to each other.

sortAndGroupAnagram

var sortAndGroupAnagram = function(array){
    var result = {};
    var sortedResult = [];
    var currentKey;
    var allKey;
        
    for (var i = 0; i < array.length; i++){
        currentKey = array[i].split('').sort().join('');
        if ( result.hasOwnProperty(currentKey) ){
            result[currentKey].push(array[i]);
        } else {
            result[currentKey] = [ array[i] ];
        }
    }

    allKey = Object.keys(result);
    allKey.sort();
    for ( var j = 0; j < allKey.length; j++){
        sortedResult = sortedResult.concat(result[allKey[j]]);
    }

    return sortedResult;
}

//var array = ["apple", "ybab", "zibra", "pplea", "arbiz", "baby", "lppae"];
//var temp = sortAndGroupAnagram(array);

//console.log(temp);
