Can you explain the techniques you use to ensure front-end security?

"As a front-end developer, security is one of my key concerns, second only to the performance of the website. By incorporating security practices in the code's original development, I eliminate the need to constantly fix leaks or combat hacks. My first step in this process is to use a framework that handles security automatically. Examples of this include View, Angular, and React. I've also begun incorporating Trusted Types into my development. This is a new browser API from Google which addresses XSS issues. Finally, I compartmentalize the individual applications rather than deploying them as a single piece of code. This makes them harder to hack and minimizes the damage when there are penetrated."
