面试 - encodeURI与 encodeURIComponent的区别？

都是对URL进行编码，区别是编码的范围不同；

encodeURI 范围小，不编码：“ACII字母、数字、~!@#$&()=:/,;?+* ”
encodeURIComponent范围大，不编码：“ASCII字母、数字、~!*()”

举例：

const url=http://www.cnblogs.com/season-huang/some other thing

encodeURI(url);
//http://www.cnblogs.com/season-huang/some%20other%20thing

encodeURIComponent(url)
//http%3A%2F%2Fwww.cnblogs.com%2Fseason-huang%2Fsome%20other%20thing
