JavaScript tooling has a blind spot: codebase-wide questions - Bart Waardenburg - Fallow -dotJS 2026

Why watch

Bart Waardenburg presents Fallow, a Rust-native codebase intelligence tool for TypeScript and JavaScript that fills a gap in AI-assisted development. The talk explains why AI agents lack system context—such as dead exports, module cycles, and architectural drift—and how graph-based analysis plus runtime evidence creates a deterministic truth layer for safe code deletion. For developers working on large JS/TS codebases who want to catch quality issues before they become technical debt.
