Good job!
In the real world, URLs are usually encoded with percent encoding to represent special characters. In URL, & can be used as a separator (key=value&key=value...) or special character within a key or value. if we were to use & as a special character, we need to encode it.

Can you refactor the code so that parseQueryString("a%25b=c%26d") results in { "a%b": "c&d" }?
FYI, %25 is same as %, %26 is same as &

function parseQueryString(queryString) {
const queryParams = {};
if (queryString.length === 0) {
return queryParams;
}

const keyValuePairs = queryString.split("&");

for (const pair of keyValuePairs) {

const decodedPair = decodeURIComponent(pair);


const [key, ...value] = decodedPair.split("=");
const newValue = value.join("=");

// Store the decoded key and value in the queryParams object
queryParams[key] = newValue;

}

return queryParams;
}

module.exports = parseQueryString;
