Coding Challenge - #7: Query String Parser

programming web dev
1

Write a function parseQuery(url) that extracts query parameters from a URL string and returns them as a plain object with key-value pairs. Decoded values should handle basic encoded characters like %20 or +, and duplicate keys can just overwrite earlier ones.

function parseQuery(url) {
  // your code here
}

Rules:

  • Return a plain object of key-value string pairs
  • Return an empty object if the URL contains no query string
  • Use built-in web standard APIs like URLSearchParams or URL, or parse manually
