How to remove spaces on both sides of a string using trim() in js

Removing spaces at both ends of a string in js can be achieved using regular expressions:

String.prototype.trim=function() { return this.replace(/(^\s*)|(\s*$)/g, ""); }

Of course the usage is very simple,

var str =" Hi,My Name is Water! ";
str.trim();

Of course you can also write a function yourself, or some people are used to this:

function trim(stri) { return stri.replace(/(^\s*)|(\s*$)/g, ""); }
var str =" Hi,My Name is Water! ";
trim(str);
