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 based on a subset of JavaScript syntax and is commonly used for transmitting data in web applications.
JSON Syntax
JSON data is written as key/value pairs, similar to JavaScript object literals. It supports the following data types:
- Objects: Collections of key/value pairs enclosed in curly braces {}
- Arrays: Ordered lists of values enclosed in square brackets []
- Strings: Text enclosed in double quotes ""
- Numbers: Integer or floating-point
- Booleans: true or false
- null: Represents no value
