-Returns a key-value pairs of object of query params of given url.
+Generates an object from the given query string or URL.
 
-- Use `String.prototype.split()` to split url .
-- Return the object of key value pair of query params of given url.
+- Use `String.prototype.split()` to get the params from the given `url`.
+- Use `new URLSearchParams()` to create an appropriate object and convert it to an array of key-value pairs using the spread operator (`...`).
+- Use `Array.prototype.reduce()` to convert the array of key-value pairs into an object.
