It had this great hook called useQueryParam which let you manage 1 query parameter in the same way as useState worked.. One great thing about useQueryParam is that it respects all other queries that you currently store in the url. It is an iterable object that lets us get the keys and values easily. URLSearchParams.keys () Logging searchParams directly gives us a URLSearchParams object, which is quite difficult to inspect the values by default due to the way it's composed and the underlying Symbol.iterator (which we'll save for another time). The URLSearchParams interface specifies the utility methods to work with the query string of a URL. Meaning it only updates the value that you set .

As you can see above, we initialize a queryParameters variable by creating a new URLSearchParams instance with the current window.location.search as a parameter.. URLSearchParams extracts the queries from the parameter passed at construction (window.location.search) and provides a set of functionalities (get, getAll, has, etc.). The advantage of using query-string is that it returns a JavaScript Object and it has additional features. URLSearchParams.has () Returns a boolean value indicating if such a given parameter exists. instead of const value = obj[key] do const value = keyFn(obj).Another approach would be to pass a key with dots, like 'color.value' and have the function . In our code, we can treat them the same as regular strings. Below programs illustrates the use of urlSearchParams.get () method in Node.js: Creating URLSearchParams Objects.
