How do I handle query strings in a URL?

You can handle query strings by using the URLSearchParams interface in JavaScript. It allows you to easily access and manipulate the query parameters.

Can you give me an example of how to use URLSearchParams?

Sure! Here's a simple example:

const url = new URL('https://example.com?name=John&age=30');
const params = new URLSearchParams(url.search);
console.log(params.get('name')); // John
console.log(params.get('age')); // 30

What if I want to add a new query parameter?

You can use the append method to add a new parameter. For example:

params.append('city', 'New York');
console.log(params.toString()); // name=John&age=30&city=New+York

Is there a way to remove a query parameter?

Yes, you can use the delete method to remove a parameter. For example:

params.delete('age');
console.log(params.toString()); // name=John&city=New+York
