A short story about the horrors we had to face while working on someone else's code, how we managed to master ourselves and start simultaneously adding new features and slowly modernizing the old ones. About how to understand a week in four pages and why legacy is not always bad, but on the contrary — a great opportunity to pump yourself up.

A common task in modern JS is parsing, validating and then comparing JSON objects.

Should we take a look at JavaScript when everyone is writing in TypeScript? What happens to the standard? What did we get last year? What new features can we expect this and next year?

Nick Gicinto, a cybersecurity leader with over 25 years of experience, who has worked for the CIA and has built security systems from scratch at Tesla and Uber, fully hiring teams for these projects, will talk about the importance of being vulnerable to build trust within a team.
