Talk to a mentorSame feature, two runtimes: code side by side
A simple HTTP server that returns JSON — see how Node.js and Deno differ.
const http = require("http"); const server = http.createServer((req, res) => { res.writeHead(200, { "Content-Type": "application/json" }); res.end(JSON.stringify({ message: "Hello from Node.js", runtime: process.version })); }); server.listen(3000);
Node.js typically uses CommonJS (require) and the built-in http module. Full access to the system by default.
import { serve } from "https://deno.land/std/http/server.ts"; serve((req) => { return new Response(JSON.stringify({ message: "Hello from Deno", runtime: Deno.version.deno, }), { headers: { "Content-Type": "application/json" }, }); }, { port: 3000 });
Deno uses ES modules with URL imports, built-in TypeScript and a secure-by-default model — you must allow network access explicitly.
Salary & job roles in India (2026)
Indicative ranges for Node.js developers — Deno roles are rare in India, so Node.js remains the practical choice for employment.
Indicative ranges only. Actual pay varies by city (Bengaluru, NCR, Pune and Hyderabad usually pay more), company, skills and experience. Career assistance does not guarantee a job or a specific package.

Frequently asked questions: Node.js vs Deno
Answers to what freshers and developers ask us most.
Which pays more in India in 2026: Node.js or Deno?
Pay depends far more on your skills, projects and company than on the runtime name. Node.js has vastly more openings — indicatively ₹3–6 LPA for freshers and ₹6–12 LPA with 2–4 years of experience. Deno roles are rare in India, so salary data is limited; where they exist, they tend to be at modern startups and can pay in a similar or slightly higher band for strong TypeScript developers. For practical employability, Node.js remains the safer bet in 2026.
Is Deno easier to learn than Node.js for a beginner?
In some ways yes, in others no. Deno is more secure by default, has built-in TypeScript, formatting, linting and testing, so you need fewer tools. But it requires understanding ES modules, import URLs and permissions. Node.js has far more tutorials, a larger community and more examples, which often makes learning easier in practice. Most beginners still start with Node.js.
What is common between Node.js and Deno?
Both are JavaScript/TypeScript runtimes built on the V8 engine. Both can run server-side JavaScript, build APIs, and support npm packages (Deno now supports npm). Both are created with JavaScript in mind, and Deno was created by Ryan Dahl, the original creator of Node.js.
Can I switch from Node.js to Deno later in my career?
Yes, and the transition is relatively smooth. Since Deno runs JavaScript/TypeScript and supports npm, much of your knowledge carries over. The main differences are permissions, import URLs, built-in tooling and the module system. A Node.js developer can usually become productive in Deno within 1–3 weeks of focused practice.
Which one should a fresher choose for placements?
For placements in India, Node.js is the clear choice — it has vastly more job openings, a huge ecosystem and is used by nearly every company building JavaScript backends. Deno is worth learning for awareness and modern tooling, but it is not yet a primary hiring skill in the Indian job market.
Does Deno support npm packages?
Yes. Since Deno 1.28, npm packages are supported natively via npm: specifiers. You can use many popular Node.js libraries, though some deeply Node-dependent packages may still have compatibility issues. Deno also has its own module registry (JSR) and supports URL-based imports.
How long does it take to become job-ready in Node.js or Deno?
With regular practice, most learners need 3–5 months for Node.js: JavaScript fundamentals, Node core modules, Express, databases, auth, deployment and 2–3 portfolio projects. Deno can be learned in 1–3 weeks on top of that if you already know Node.js. Prior programming experience shortens this.
