Learners will receive a Certificate of Completion from Uplatz, validating their expertise in Deno 2.0 and modern runtime development. This certification demonstrates readiness for roles in backend engineering, full-stack development, and cloud-native applications.

Deno 2.0 skills prepare learners for roles such as:

• Backend Developer (JavaScript/TypeScript)

• Full-Stack Engineer (Fresh, Aleph.js, Oak)

• API Developer (REST/GraphQL)

• Software Engineer (secure apps)

• DevOps Engineer (runtime optimization)

Deno is increasingly being adopted as a secure, modern alternative to Node.js, making it valuable for startups and enterprises focused on performance and safety.

1. What is Deno 2.0?
A modern JavaScript/TypeScript runtime built with security and simplicity in mind, offering built-in TypeScript, ES modules, and permission control.

2. How does Deno differ from Node.js?
Deno is secure by default, uses ES modules, has built-in TypeScript support, and does not rely on package.json or npm.

3. What is Deno’s permission system?
A security model requiring explicit permission flags (--allow-read, --allow-net, etc.) for accessing resources.

4. Can Deno run npm packages?
Yes, Deno 2.0 includes compatibility with npm packages.

5. What are some use cases for Deno?
REST APIs, CLI tools, real-time apps, microservices, and cloud-native applications.

6. What are the benefits of Deno 2.0?

• Security by default

• Built-in TypeScript and ES modules

• Simplified dependency management

• Strong developer experience

7. What are challenges with Deno?

• Smaller ecosystem compared to Node.js

• Limited enterprise adoption

• Learning curve for developers used to Node.js tooling

8. What frameworks are available for Deno?
Fresh, Aleph.js, and Oak are popular frameworks for building apps with Deno.

9. How does Deno Deploy work?
A cloud platform by the Deno team to run Deno apps globally at the edge with zero configuration.

10. Where is Deno being adopted?
By developers, startups, and companies looking for secure, TypeScript-first runtimes as alternatives to Node.js and Bun.
