Functional Programming in SCALA

on YouTube ↗50m

" summary

Quick tour of SCALA basics that demonstrates actual code: REPL demos, immutable collections by default with a separate mutable package, higher‑order functions like map/filter applied to List/Vector/Set/Map, tuples and default args, and Java interoperability. A simple profiler returns (result, millis). Parallel collections via .par halve wall time on a fib benchmark (sequential Vector of 43s ~9.5s, parallel ~4.9s). Examples compile and run.
