Introduction to functional programming

" summary

Fast, concrete demo of replacing imperative loops with JavaScript higher‑order functions: live code shows a pantry→breakfast taco example refactored from for‑loops that mutate arrays into map filter reduce calls that return new collections, an explicit pipe implementation that composes functions, and explanation of eliminating side effects to make pure functions. Mentions the TC39 pipeline operator proposal and links code on GitHub: badali/end-of-loops.
