Read open source code. It is the cheapest way to improve. Find patterns working for hundreds of people. Use them.
Here are three patterns for 2026.
The satisfies operator Stop using standard types for configs. Standard types remove literal values. Use satisfies. It checks the shape. It keeps specific values. Your autocomplete stays sharp. Your types stay accurate.
Branded Types Strings are dangerous. You might pass a Post ID into a User function. TypeScript will not stop you. Create branded types. Give your strings a unique label. The compiler now sees them as different. Bugs stop before they ship.
The kind field Avoid optional booleans for state. Stop using isLoading and isError. Use a discriminated union. Add a kind field. Use values like loading, success, or error. TypeScript narrows the type for you. You see data only when the state is success.
Reading source code is professional development. It beats a bootcamp. Pick one codebase you like. Read it for 30 minutes this week. Find one pattern. Use it on Monday.
