TypeScript may streamline code navigation and catch semantic errors, but it doesn't guarantee fewer bugs or faster fixes.

Understanding the nuances of TypeScript: it adds static types to JavaScript, reducing bugs by checking code validity pre-run. But imagine if we had types at run-time too - validating inputs, enhancing error messages. A dream, but a nice one.

I've been using Bun in a few side-projects and I like it a lot

DynamoDB Streams are a convenient way to react to changes in your database. And surprisingly easy to use 🥳

The cult of TDD leads you down a dark and stormy path towards brittle code with a false sense of security. But there is a better way. A sweet spot between unit and heavy integration.

Every null or undefined check doubles the number of tests you need 😱

Using plain Jest on a TypeScript codebase is kinda rough. No types in tests no thanks. Making Jest and TypeScript work together smoothly is something you do just rarely enough to forget the details. Hope this helps you and future me too ✌️

TypeScript solves many of JavaScript's sharpest edges. You don't need much to get started ✌️

A hill I will die on 👉 global CONSTANT = 'constant' are bad

Reusable hooks are all fun and games until TypeScript starts yelling at you about incompatible types.
