sort()方法

//数组排序
var n = [15, 99, 23, 42, 4, 8, 16];
n.sort(function(a, b) {
    return a - b
});
console.log(n);

//字符串排序
var m = ['aa', 'bb', 'a', 4, 8, 15, 16, 23, 42];
m.sort(function(a, b) {
    if (a === b) {
        return 0;
    }
    if (typeof a === typeof b) {
        return a < b ? -1 : 1;
    }
    return typeof a < typeof b ? -1 : 1;
});
console.log(m);

//名字比较
var by = function(name, minor) {
        return function(o, p) {
            var a, b;
            if (o && p && typeof o === 'object' && typeof p === 'object') {
                a = o[name];
                b = p[name];
                if (a === b) {
