What is JSON?
JSON (JavaScript Object Notation) is a lightweight data interchange format. It's easy for humans to read and write, and easy for machines to parse and generate. JSON is the most common format for API responses and configuration files.
JSON Syntax Rules
- Data is in name/value pairs:
"name": "value" - Data is separated by commas: Multiple items are comma-separated
- Curly braces hold objects:
{ "key": "value" } - Square brackets hold arrays:
["item1", "item2"] - Strings use double quotes:
"text"(not 'text')
JSON Data Types
| Type | Example | Description |
|---|---|---|
| String | "Hello" | Text in double quotes |
| Number | 42, 3.14 | Integer or floating point |
| Boolean | true, false | Logical values |
| Null | null | Empty value |
| Object | {"key": "value"} | Collection of key-value pairs |
| Array | [1, 2, 3] | Ordered list of values |
