You know Python's clean syntax and dynamic typing. TypeScript adds a compiler, static types, and the entire JS ecosystem.
From Python defs to TypeScript functions
Python classes with enforced access modifiers in TypeScript
Explicit exports vs Python's implicit public API
From Python's asyncio to JavaScript Promises
TypeScript in the browser — no Python equivalent
Reusable typed functions and classes
Mapped types, conditional types, template literal types, and satisfies operator
TypeScript uses try/catch with Error objects; Python uses try/except with a rich exception class hierarchy. Custom errors extend Error in TS vs Exception in Python.
