"Tell me a design pattern and explain how it works" is one of the main questions in a technical job interview.

In this session, you will add one more skill to your arsenal: a new design pattern, the Publisher/Subscriber, or PubSub for those more familiar.

Easy, intuitive, and extremely important for projects that involve real-time collaboration.

There have been many react component patterns used over the years to facilitate the composition of frontend software.

However, React has evolved over the years especially with the introduction of hooks and context. Newer ways to do things clash with the so-called "older ones". In my talk, I want to take a relook the patterns from the perspective of a developer's needs for implementation, be it extracting logic, combining props, handling hierarchy, or inverting control of state.

Once the need is established, it is helpful to compare the new and the old patterns, if they exist, for the same goal and understand the pros and cons of each.
