JSON 3 (v80)

Revision 80 of this benchmark created on

Description

This test benchmarks JSON 3 against other JSON implementations.

The following implementations support parsing and serializing:

  • JSON 3: Uses a modified, character-based recursive descent parser.
  • JSON 2: Uses eval and a series of validation RegExps.

The following implementations only support parsing:

  • json-parse: Uses a character-based recursive descent parser.
  • json-parse-state: Uses a state machine parser.
  • json-sans-eval: Uses a non-validating RegExp.
  • evalJSON: Uses a RegExp-based recursive descent parser.
