Node.js vs. Deno: Which runtime is better for Backend development?

Node.js and Deno are both JavaScript runtimes, but they differ in security, performance, and developer experience. Node.js is the most widely used runtime, offering a huge package ecosystem (NPM), asynchronous programming support, and a strong community. Deno, created by the original Node.js developer, improves on security, modern module handling, and built-in TypeScript support.

If you need a stable ecosystem and vast third-party libraries, Node.js is the better choice. However, if security, TypeScript integration, and modern features are a priority, Deno offers a more secure, modern approach.

Key Takeaways:

• Node.js → Best for enterprise apps, NPM package support, and compatibility.

• Deno → Ideal for secure, TypeScript-first applications with built-in tools.

• Deno has stricter security defaults, while Node.js has broader ecosystem support.
