Learners will receive a Certificate of Completion from Uplatz, validating their expertise in Bun Runtime and modern JavaScript development. This certification demonstrates readiness for roles in backend development, full-stack engineering, and high-performance web applications.

Bun Runtime skills prepare learners for roles such as:

• Backend Developer (JavaScript/TypeScript)

• Full-Stack Engineer (React, Next.js, Bun)

• API Developer (REST/GraphQL)

• Software Engineer (high-performance apps)

• DevOps Engineer (runtime optimization)

Bun is rapidly gaining adoption as a high-performance alternative to Node.js, making it an attractive skill for startups and enterprises adopting modern runtimes.

1. What is Bun Runtime?
A modern JavaScript/TypeScript runtime written in Zig, designed for speed and simplicity, with a built-in package manager, bundler, and test runner.

2. How does Bun differ from Node.js?
Bun is significantly faster, natively supports TypeScript/JSX, and includes tools like a package manager and bundler, which Node.js requires separately.

3. What languages does Bun support?
JavaScript, TypeScript, JSX, and JSON natively, without extra transpilers.

4. What is the Bun package manager?
A built-in alternative to npm/yarn/pnpm, optimized for speed, using bun install.

5. Can Bun run existing Node.js packages?
Yes, Bun is designed to be compatible with most Node.js/npm packages.

6. How does Bun handle testing?
It includes a built-in test runner, removing the need for external libraries like Jest.

7. What are the benefits of Bun?

• High performance

• All-in-one tooling (runtime, bundler, test runner, package manager)

• Native TypeScript support

• Simplicity in setup and usage

8. What are challenges with Bun?

• Ecosystem is still maturing

• Some Node.js packages may not be fully compatible

• Limited production use cases compared to Node.js

9. What are real-world use cases of Bun?
REST APIs, real-time apps, CLIs, e-commerce backends, and full-stack JS/TS projects.

10. Where is Bun being adopted?
By startups, experimental projects, and performance-focused teams looking for alternatives to Node.js and Deno.
