In this episode we'll talk about associative containers: containers that map arbitrary keys to values. What are the ones that are provided by Qt? Are there differences between their Qt 5 versions and their Qt 6 versions? Which one should one pick for a given use case? No spoilers – watch until the end (Lächeln)

In the video, we mention a couple of blog posts about how to implement hashing functions. Here they are:
