How to get GET parameter values from URL in JavaScript?

Hi everyone! I'm a beginner in JavaScript and I've encountered this task: I have a page that opens with GET parameters in the URL, for example:\n\n```\nhttps://example.com/page?name=John&age=25&city=New%20York\n```\n\nI need to extract the values of these parameters (name, age, city) and use them in the code. I tried using `window.location.search`, but it only returns the string `?name=John&age=25&city=New%20York`. I don't know how to parse it further. I attempted to write my own function using `split('&')`, but I'm confused about decoding characters (e.g., `%20` instead of a space) and handling special characters. There's also the issue if a parameter is repeated (e.g., `?id=1&id=2`). Please advise on how to correctly and reliably get all parameters as an object? Preferably without jQuery, just plain JavaScript. Thanks.
