Web development today is more than just HTML and JavaScript—it’s a constantly evolving field that spans backend logic, data handling, deployment, UI design, and architectural thinking.

Backend development starts with understanding how your code runs behind the scenes—and Node.js is your gateway to scalable, JavaScript-powered servers.

What if your code wasn’t just functional—but expressive, modular, and built for the real world? This beginner-to-intermediate bootcamp shows you how.

Featuring 12 code-based challenges with unlimited attempts, this hands-on test lets you master browser-based security concepts through real attack simulations. Use a built-in JavaScript environment to understand the Same-Origin Policy, exploit Cross-Site Request Forgery (CSRF) vulnerabilities, perform cross-origin requests, analyze SameSite cookies, exploit weak CORS policies, and walk through a case study on CSRF exploitation. Each task reflects real-world exam scenarios, preparing you to actively script and simulate cross-origin attacks.

Featuring 8 code-based challenges with unlimited attempts, this hands-on test dives into JavaScript prototype pollution and template engine exploitation. Discover and exploit prototype pollution, and achieve remote code execution through EJS and Handlebars templates. Each task mirrors real-world exam scenarios, helping you script and execute advanced JavaScript-based attacks.

JavaScript powers everything from interactive websites to powerful web apps—and it’s one of the most in-demand programming languages in the world. Whether you're brand new to coding or switching from another language, this course gives you the hands-on foundation you need to start building with confidence.
