## What it is
A pure JavaScript JSON parser and validator with a command-line interface, a JavaScript version of lint.com. It reports detailed syntax errors or pretty-prints valid JSON, and can also validate against JSON Schema.

## Use cases
- validate  files from the command line
- pretty print  with custom indentation
- find syntax errors in a  config file
- validate  against a  schema
- sort  object keys
- lint  in vim via syntastic or ale

## When to avoid
- you only need to parse JSON in JavaScript code (use built-in JSON.parse)
- you need an actively maintained tool with ongoing updates
- you need a license-guaranteed dependency (no explicit license file)

## Facets

- maturity: maintenance
- function: parser, linter, cli
- domain: developer-tools, files
- platform: cli, cross-platform
