+# Deno Case Study
+
+## Introduction
+
+Deno is a modern runtime for JavaScript and TypeScript, created by Ryan Dahl — the original creator of Node.js. It was designed to fix the shortcomings of Node.js with better security, a simplified module system, and built-in TypeScript support.
+
+## History
+
+Deno was first introduced in 2018 during a talk titled “10 Things I Regret About Node.js.” Ryan Dahl created Deno as a fresh take on a server-side JavaScript runtime, addressing problems like package management and lack of built-in security. Deno reached its stable 1.0 release in May 2020.
+
+## Applications and Use Cases
+
+- Running JavaScript/TypeScript outside the browser
+- Web servers and API backends
+- Command-line tools
+- Serverless functions
+- Scripts for automation
+
+## Strengths
+
+- **Security by default**: No file, network, or environment access unless explicitly enabled
+- **Built-in TypeScript support**: No separate compiler needed
+- **Simplified module imports**: Uses URLs instead of `node_modules`
+- **Built-in tooling**: Includes formatter, linter, test runner, and bundler
+
+## Weaknesses
+
+- **Smaller ecosystem**: Less mature than Node.js
+- **Fewer libraries**: Not all Node.js packages are compatible
+- **Learning curve**: New conventions and APIs
+
+## Comparison with Node.js
+
+| Feature            | Deno                             | Node.js                         |
+|--------------------|----------------------------------|----------------------------------|
+| Language Support   | JavaScript & TypeScript          | JavaScript (TypeScript optional) |
+| Security           | Secure by default                | No security by default          |
+| Package Management | No `node_modules`, uses URLs     | Uses npm and `node_modules`     |
+| Tools              | Built-in (test, lint, fmt)       | Requires installing tools       |
+| Ecosystem          | Smaller but growing              | Very large and mature           |
+
+## Conclusion
+
+Deno is a powerful and secure alternative to Node.js, especially for developers who want built-in TypeScript and modern tooling. While its ecosystem is still growing, it offers a cleaner and more secure approach to building JavaScript applications for the backend or CLI.
