TypeScript Feature Matrix

This directory contains a small compatibility radar for TypeScript and modern JavaScript language features. Each probe is a standalone .ts file that Node runs with --experimental-strip-types; Perry compiles the same file to a native binary and the generator records whether stdout matches.

Regenerate the committed matrix after adding probes or intentionally changing language behavior:

python3 scripts/gen_feature_matrix.py --perry-bin target/release/perry

Check that the committed matrix is current:

python3 scripts/gen_feature_matrix.py --check --perry-bin target/release/perry

Current failures are allowed in feature_matrix.md; the CI check only detects drift between the probes and the committed baseline.
