Get key value from url

Suppose your have a url www.someexample.com?email=aditya%40rensoriginal.com&utm_campaign=VIP%20request%20US%20%28%20%2B%20no%20listed%20country%29%20%28RMd2wQ%29&utm_medium=email&utm_source=everyone%20without%20a%20country&_ke= and you want to get the email and it’s value.

Here, I will provide two solutions for above problem, one with regex and one without regex. Let’s see the first one with regex.

function getUrlVars() {
  var vars = {};
  var parts = urlString.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
    console.log({m})
    vars[key] = value;
  });
  console.log({vars})
  return vars;
}

Another solution without regex,

function getUrlVars() {
  return urlString.split('?')[1].split('&').reduce((final, cv) => {
    const [key, value] = cv.split('=')
    return {
      ...final,
      [key]: value
    }
  }, {})
}
