Part 1

Write a function that takes a string URL and a query object and returns the URL with a query string added.

Example:

function stringifyUrl(url, query) {
    // your code here
}

const url = "http://localhost:8080/monkeys"
const query = {
    color: "black",
    species: "howler"
}

stringifyUrl(url, query)
// returns "http://localhost:8080/monkeys?color=black&species=howler"

Part 2

Write a function that does the opposite from above: given a valid URL with a query string attached, return a query object.
