## What it is
11 is a tiny JSON library for C++11 providing JSON parsing and serialization through a value-type Json object. It supports initializer-list construction, implicit conversion from user types, and query methods for inspecting parsed values.

## Use cases
- parse  strings in c++
- serialize c++ objects to
- build  objects with initializer lists
- read values from parsed  documents
- embed a minimal  parser without heavy dependencies

## When to choose
- you need a small, dependency-free JSON library for C++11
- you want simple value-semantics JSON objects with parse and dump
- your project only needs basic JSON parsing and serialization

## When to avoid
- you need high-performance or standards-compliant JSON with full feature coverage
- you need JSON schema validation, streaming, or SAX-style parsing
- you want an actively developed library with ongoing fixes

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, parser
- domain: developer-tools, apis
- platform: cpp, cross-platform
- tags: c++11, header-only-friendly, lightweight
