关于字符串中每个单词的首字母大写化问题之 拆分split(/\s+/)

var a = 'Hi, my name\'s Han Meimei, a SOFTWARE engineer';

//for循环
function titleCase(s) {
    var i, ss = s.toLowerCase().split(/\s+/);
    for (i = 0; i < ss.length; i++) {
        ss[i] = ss[i].slice(0, 1).toUpperCase() + ss[i].slice(1);
    }
    return ss.join(' ');
}
console.log(titleCase(a));
