Have you ever wondered how Web or mobile frontend application would look like if someone missed completely the point of reactivity applied to frontend development?

Me neither. Until I saw an application written in a mixture of imperative and declarative style, that has organically transformed into a tangled mess of code, confusing everyone including original developers. Worse yet, had to deliver results within a few weeks.

In the talk, we'll get through a example resembling that project and see how to work with such code in the times of peace and times of emergency. We'll get through:
1. Principles of reactivity in modern frontend applications
2. Approaches to set and communicate responsibility boundaries in code
3. What mindsets are useful in times of emergency and in times of peace.

This is an intermediate talk which aims to give you a glimpse of your career in the future if you're a younger developer and will give you tangible tips if you're an experienced developer.
