> In 95% of programming activities, the traditional "real computer science (what is "fake" computer science?), algorithms, data structures, number theory, probability" are used surprisingly rarely Yeah, unfortunately, the cheap webshits use reverse loops because they read in some medium article that comparison to zero is shorted, while repeatedly concatenating strings in an inner loop. Doesn't help with things like - indexing on utf-8 strings is O(n) and often the compiler/JIT is not able to figure out all necessary loop fusions for you. Basic algorithms, data structure knowledge is a must for every programmer. I don't say they should know how to prove a treap is 0.yz times more efficient than a skiplist. Now the next part. > while the elegance of functional/mathematical reasoning ... There is natural reasoning and there is category theory stuff that only serves to signal the dude has studied some aBsTrAcT mAtHeMaTiCs in programming communities. A best example of this is Haskell. They bastatdized quicksort to show an "elegant example" on their website. Another example is react. "React is fast omg virtual DOM". Not everyone will have latest macbook pro like hipster webshits. I know, and I acknowledge the improvements in craft of ~~CRUD WEBSHIT~~ programming that came from FP camps. But there is also lot of bullshit there in FP camps.
