vercel-labs/scriptc v0.0.4 on GitHub

console.log prints every inspectable shape: arrays, records, Maps/Sets, class instances, undefined/null, Buffers, and unions — each non-scalar argument renders through the same machinery as util.inspect, matching Node's console semantics exactly (string union arms print raw, format-string first arguments keep util.format behavior).
The #private members chain: private fields, instance and static methods, accessors, generator methods, and #x in obj brand checks all compile, with Node's lexical binding and brand semantics.
node:querystring compiles statically: the full legacy surface (parse, stringify, escape, unescape) with Node's exact separator, maxKeys, and malformed-escape behavior.
Command-table and generic-member patterns: as const option tables with String/Number/Boolean constructor values, generic arrow instance fields, async generic methods and statics, and definite-assignment (field!) declarations all lower.
Object literals widen per-field into union arms: the reducer-action pattern — a literal whose fields fit exactly one arm of a contextual union — now compiles.
The performance global, Response.headers/arrayBuffer()/bytes(), and Math.max/Math.min at any arity.
Workspace members install-agnostic: monorepo siblings classify identically whether the package manager symlinks or copies them into node_modules.

Whole-program IR validation over large mixed static/dynamic graphs no longer surfaces internal errors: island values entering typed intrinsic slots are validated at the boundary, and any-typed values dispatch through the checked-dynamic machinery.
JSON.stringify of a dynamic value holding undefined now prints identically on both backends.
Loose equality between same-kind operands lowers as strict equality.
The limitations page documents the type surface: where scriptc's ambient world is narrower than stock TypeScript's, and what diagnostics point at instead.
