There is an infinite discussion about the topic of knowing algorithms and data structures for a frontend (in my case, mobile) developer needed only to pass technical interviews in large tech companies, or if there is some benefit of using it in daily work. I think the truth is somewhere in between, as always. Of course, you rarely find a case when you need to implement a min heap or use dynamic programming approaches while working on UI and business logic for a service with a REST API, but having a basic understanding of performance, time, and memory complexity can help make small, simple optimizations in the app that can pay off a lot in the long run.
I want to give an example of such a small optimization and decision-making process that can help us decide whether the extra effort is worth it or not.
