Transforming your C# code to Functional Style

on YouTube ↗43m

" summary

Shows concrete C# rewrites: replace for/foreach and mutable accumulators with LINQ Where/Select and passing lambdas, turning imperative loops into internal iterators that produce new collections without explicit mutation. Demonstrates laziness of intermediate ops (no work until a terminal call like ToList or First) and easy parallelism via parallel collections/PLINQ, applies tell‑don’t‑ask and single level of abstraction by moving booking logic into a bookIfAvailable method, and reports that these changes make code shorter, safer and trivially parallelizable.
