JS-Static-Call-Graph

Large JavaScript files can hide the path from one function to another. Before changing behavior, it's useful to see the call relationships without reading the whole file line by line.

• Parse source files and extract function declarations and call expressions from the AST.
• Generate a graph that favors readable relationships over compiler-level completeness.
• Support code review, onboarding, and refactoring where control flow needs a quick audit.
• Keep the tool small instead of turning it into a broad analysis platform.

• Static parsing won't capture every runtime path, so the graph is a review aid rather than a final authority.
• The output avoids excess detail because the main job is quick inspection.
• Plain inputs and outputs make the tool easier to use inside an existing codebase.
