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 Form Data?
form data (URL-encoded) is the standard format for submitting HTML form data to web servers. It encodes form fields as key-value pairs using percent-encoding for special characters.
Form data encoding (application/x-www-form-urlencoded) is the standard format for HTML form submissions. It is used for:- User Registration: Submitting login and signup forms.
- Search Forms: Encoding search criteria for HTTP GET/POST.
- Legacy APIs: Supporting traditional form-based API endpoints.
