## What it is
A fast and simple JSON Schema validator for JavaScript and Node.js, supporting JSON Schema versions through draft-07. It validates objects against schemas including references, arrays, formats, and required fields.

## Use cases
- validate  payloads against a schema
- validate api request bodies with  schema
- check config files match a  schema
- validate nested objects with $ref references
- validate arrays of objects in javascript
- enforce required fields and types on  data

## When to choose
- you need JSON Schema draft-07 validation in Node.js
- you want a lightweight, fast validator with a simple API
- you need support for schema references and split schemas

## When to avoid
- you need draft 2019-09 or 2020-12 support
- you need a browser-first or TypeScript-native validator
- you need detailed error localization or i18n
