I'm really concerned about security when it comes to programming, particularly in frontend development, but I know it applies to all areas. I feel uncertain about what specifically to look for and how to ensure that the code I write is actually secure. Can anyone recommend some good resources that cover security comprehensively? Also, I would appreciate a quick rundown of key concepts.

Check out the OWASP Secure Coding Practices Quick Reference Guide; it offers a solid list to get you started on security best practices. Security is broad and contextual, so while it might not be an exhaustive guide, it will definitely help you focus on critical areas.
The OWASP Cheat Sheet series is also a great resource for learning security essentials. Remember that in frontend development, while security issues can seem less critical, any oversight can lead to serious risks. At the very least, review the OWASP Top 10 to avoid common vulnerabilities.
A good rule of thumb is to never trust user input. That might sound simple, but many developers overlook it. For instance, some people fail to recognize that even data from server access logs can be treated as user input, which needs to be sanitized.
It's crazy how many don't grasp that concept. Input from any source should always be treated with caution.
Regarding vulnerabilities reported with node modules, should I look into those? I've heard mixed feelings about their importance.
