#architecture #code #cognition #complexity #reading | When reading code, you put things like values of variables, control flow logic and call sequences into your head. The average person can hold roughly four such chunks in working memory. Once the cognitive load reaches this threshold, it becomes much harder to understand things. Let's say we have been asked to make some fixes to a completely unfamiliar project. We were told that a really smart developer had contributed to it. Lots of cool architectures, fancy libraries and trendy technologies were used. In other words, the author had created a high cognitive load for us.
