Which one is best for a Node.js API: ES6 or TypeScript?

When building a Node.js API, both ES6 and TypeScript offer strong capabilities, but TypeScript provides better type safety and scalability. ES6 is the standard JavaScript version, offering modern syntax like arrow functions, async/await, and modules, while TypeScript extends ES6 with static typing, interfaces, and advanced tooling.

If you need faster development with JavaScript flexibility, ES6 is great. If you want better error detection, maintainability, and scalability, TypeScript is the better choice for a Node.js API.

Key Takeaways:

• ES6 → Best for small projects, fast prototyping, and lightweight APIs.

• TypeScript → Ideal for enterprise APIs, type safety, and scalability.

• TypeScript prevents runtime errors, while ES6 offers more flexibility.
