JSON 3 is a JavaScript polyfill providing spec-compliant JSON.parse and JSON.stringify for older JavaScript platforms that lack native JSON support. It is deprecated and no longer maintained, with users directed to native JSON methods.
Use cases
- add JSON support to old browsers without native JSON
- parse JSON strings in legacy JavaScript environments
- serialize JavaScript values to spec-compliant JSON
- support ES5 JSON in old runtimes like IE7
- avoid eval-based JSON parsing in legacy code
When to choose
- maintaining a legacy codebase that already depends on it
- targeting very old browsers or runtimes without native JSON
When to avoid
- starting any new project
- any environment with native JSON.parse/stringify (all modern platforms)
- projects needing maintained dependencies or security updates
