Overview

Vendored Google Closure Library module providing JSON utility functions used by Selenium JavaScript atoms.

Description

goog.json is a vendored copy of the Google Closure Library module. It provides JSON parsing and serialization utilities, including a safe JSON validator (isValid), native JSON support toggling, and a custom Serializer class. The module includes careful validation to prevent code injection via eval-based parsing. Selenium uses this as part of its JavaScript atom infrastructure.

Usage

This module is consumed internally by Selenium's JavaScript atoms build system. Not imported directly by end users.
