Liran Tal (lirantal.com) from Snyk joins us to dive deep into writing secure TypeScript applications. What's different compared to vanilla JavaScript security? Will schema validators fix all our woes? Can't we let LLMs find and fix security vulnerabilities? Liran educates us about the pitfalls and risks with misplacing trust in TypeScript and LLMs and what we can do to write more secure code.
