 * @param {string[]} words
 * @param {string} order
 * @return {boolean}
var isAlienSorted = function(words, order) {
    const orderMap = {};
    for (var i = 0; i < order.length; i++) orderMap[order[i]] = i;
    for (var i = 0 ; i < words.length-1 ; i++ ) {
        if (compare(words[i], words[i+1], orderMap) === 1) return false;
    return true;    
var compare = function(a, b, orderMap) {
    for ( var i = 0 ; i < Math.min(a.length, b.length) ; i++ ) {
        if (orderMap[a[i]] < orderMap[b[i]]) return -1;
        else if (orderMap[a[i]] > orderMap[b[i]]) return 1;
