JavascriptingFor years we wrote gross regular expressions to get query string values but those days are gone—enter the amazing URLSearchParams API:



code:
// Assuming "?post=1234&action=edit"

var urlParams = new URLSearchParams(window.location.search);

console.log(urlParams.has('post')); // true
console.log(urlParams.get('action')); // "edit"
console.log(urlParams.getAll('action')); // ["edit"]
console.log(urlParams.toString()); // "?post=1234&action=edit"
console.log(urlParams.append('active', '1')); // "?post=1234&action=edit&active=1"


keep these tricks in your toolbox for when you need them!
