Learn JavaScript Security to Build Career Advantage
When you understand security, you become more than just a builder—you become a guardian of the web. Our new free course, Introduction to JavaScript Security (LFS184), helps developers do just that.
JavaScript powers today’s web, but it’s also a frequent target for attackers. If you’re a developer, engineer, or aspiring technologist, you’re expected to write functional code—but more and more, you’re also expected to write secure code. That’s where this course gives you an edge.
Security: The New Differentiator
The best developers aren’t just shipping features—they’re spotting risks before they turn into incidents. They understand the tradeoffs in design decisions. They know how to think like a defender. That mindset isn’t just good for the codebase—it’s good for your career.
Whether you’re early in your journey or looking to level up, Introduction to JavaScript Security helps you develop that security-first mindset. You’ll learn to recognize common attack patterns, understand how browsers enforce security boundaries, and make choices that reduce risk without slowing development.
What You’ll Gain
- A practical foundation in web and JavaScript security
- Insight into how attackers exploit common vulnerabilities
- Confidence to speak the language of security in code reviews and interviews
- A credential that proves you’re serious about building safer software
This is more than just a skills course—it’s a signal to future employers that you think beyond the code. It shows you’re ready for the next step, whether that’s a new role, a promotion, or simply writing better software.
