What Is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is the most widely used data format for web APIs, configuration files, and data storage.

JSON is widely used for:

  • Web APIs: Sending data between servers and clients.
  • Configuration: Settings for applications (package.json, tsconfig.json).
  • Data Storage: NoSQL databases like MongoDB use JSON-like documents.

What Is URL Encoded?

URL encoding (percent-encoding) encodes special characters in URLs using % followed by two hexadecimal digits. It ensures that data containing spaces, symbols, or non-ASCII characters can be safely transmitted in URLs.

URL encoding ensures that special characters like spaces, &, and = are properly transmitted in URLs. It is used in:
  • Form Submissions: POST data with application/x-www-form-urlencoded.
  • API Parameters: Passing complex search or filter criteria.
  • Web Scraping: Encoding request parameters for HTTP clients.
