Frequently Asked Questions
❓ Can I use Bun in production today?
Yes, companies like Railway, Midjourney, and Canva use Bun in production. However, for enterprise projects requiring extensive support, Node.js remains the safer choice. Bun is excellent for new projects without heavy legacy dependencies.
❓ Does Deno 2 work with npm packages?
Yes! Deno 2 has excellent npm compatibility. You can import npm packages directly using the npm: prefix (e.g., import express from "npm:express"), or use traditional package.json imports. Most npm packages work without modification.
❓ Is Node.js 22 slower than Bun and Deno?
In raw benchmarks, Node.js 22 is slower for startup time and simple HTTP requests. However, for real-world applications with database connections, external API calls, and complex business logic, the performance differences are often negligible. Node.js’s mature optimization and V8 improvements make it plenty fast for most use cases.
❓ Which runtime should I learn in 2026?
For career value, learn Node.js first — it’s the most widely used and required for most jobs. Then learn either Bun or Deno depending on your interests. Many developers now use Bun for local development while deploying to Node.js in production for compatibility.
❓ Can I migrate from Node.js to Bun/Deno easily?
Migrating to Bun is relatively easy for most Node.js projects due to high compatibility. Deno migration requires more adjustment due to different module patterns and security model. Both offer Node.js compatibility layers to ease transition.
❓ What’s the future of Node.js?
Node.js isn’t going anywhere. It remains the most widely used JavaScript runtime, with strong corporate backing from IBM (via Red Hat) and an active open-source community. Node.js 22 continues improving, and the project shows no signs of slowing down.
❓ Which is best for serverless functions?
Bun is excellent for serverless due to its extremely fast cold starts. Many platforms now support Bun runtime. Deno Deploy offers serverless with integrated database (Deno KV), while Node.js remains the most widely supported across all serverless providers.
