How to get URL parameter using jQuery or plain JavaScript?

Question

I have seen lots of jQuery examples where parameter size and name are unknown.

My URL is only going to ever have 1 string:

http://example.com?sent=ye

With vanilla JavaScript, you could easily take the params (location.search), get the substring (without the ?) and turn it into an array, by splitting it by '&'.

As you iterate through urlParams, you could then split the string again with '=' and add it to the 'params' object as object[elmement[0]] = element[1]. Super simple and easy to access.

            var urlParams = location.search.substring(1).split('&'),
                params = {};

            urlParams.forEach(function(el){
                var tmpArr = el.split('=');
                params[tmpArr[0]] = tmpArr[1];
            });


            var error = params['error'];
            var type = params['type'];
