## Description

The validator is a reference static analysis tool and language specification checker designed to verify that JavaScript source code strictly adheres to the defined grammar, type rules, and structural requirements of the asm.js subset standard. By inspecting source files without execution, it acts as a syntax linter that catches structural errors, malformed syntax, and standard violations early.

The tool parses source code into hierarchical token structures to analyze grammatical correctness and language feature usage. It measures code against formal grammar definitions and matches programmatic rules against syntax nodes to enforce strict language subset constraints, utilizing recursive tree traversal to check isolated language requirements efficiently.
