Modern JavaScript Syntax Through ES2024
A practical guide to modern JavaScript syntax through an engineering lens. Learn which ES2024-era features genuinely improve code quality and which ones still need restraint.
TypeScript Generics: A Practical Guide
A practical and production-focused guide to TypeScript generics. Learn when generics improve API contracts, when they overcomplicate code, and how to keep inference readable.
Type Narrowing at I/O Boundaries
A type system is strong inside the application, but external input still needs to be narrowed and validated early. This guide explains the boundary strategy.
Defining the Boundary Between TypeScript and Runtime Schemas
TypeScript alone cannot protect external input. Teams need a clear boundary between static types and runtime validation.
Where Type Safety Ends and Runtime Validation Begins
Strong type systems do not remove the need for validation. This guide explains how production teams should divide responsibility between types and runtime checks.
How Type Systems Change API Design
A practical look at how static types, null handling, generics, and immutability shape API design quality and team productivity.
