Look, I love TypeScript. But damn, sometimes typing things like fetch() responses feels like trying to teach a cat to sit. So let me show you how I deal with it - without overengineering or writing novels in types.

Template Literal Types = dynamic, type-safe, IDE-friendly string types. Great for: API paths, CSS, event handlers, validations, enums, and much more.

satisfies makes TypeScript type-check your object without changing what it “really is”. You get safety and autocomplete. Win-win.

TypeScript 5.5 adds support for new Set methods: union, intersection, difference, and symmetricDifference. These make it easier to combine, compare, and filter sets of unique values in your code.

React stores Hooks as a singly linked list attached to each functional component, ensuring state and effects are managed in a consistent order during every render. This design allows React to efficiently track and update state, but requires that Hooks are always called in the same order and never conditionally. As a result, functional components remain predictable and stable.
