What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format. It's easy for humans to read and write and for machines to parse and generate.

Advantages of JSON Formatting

Formatted JSON improves readability, making it easier to debug and understand data structures. Minified JSON reduces file size, improving network transfer speed.

Common JSON Errors

• Missing quotes (keys must be wrapped in double quotes)
• Comma errors (no comma after the last item)
• Mismatched braces or brackets
• Invalid values (undefined, NaN, Infinity are not allowed)

JSON Use Cases

JSON is used in various areas such as web API responses, configuration files, and data storage. It's especially widely used as a data exchange format between servers and clients in web applications.
