A comparison of TypeScript and JavaScript covering the key pros and cons of adopting TypeScript. Pros include type safety, better expressability through interfaces and abstract classes, and the flexibility to opt in to types gradually (including using `any` for legacy code). Cons include the required build step (with notes on running single files via ts-node and debugging in VS Code) and the learning curve, though the author notes most differences are syntactical for those with OOP backgrounds.
