As long as you're dealing with simple ASCII characters, and you're happy to use built-in functions, this will work:

(只要您要处理简单的ASCII字符，并且很高兴使用内置函数，就可以使用：)

function reverse(s){
    return s.split("").reverse().join("");
}

If you need a solution that supports UTF-16 or other multi-byte characters, be aware that this function will give invalid unicode strings, or valid strings that look funny.

(如果您需要支持UTF-16或其他多字节字符的解决方案，请注意此函数将提供无效的unicode字符串或看起来很有趣的有效字符串。)
