" summary

Demonstrates using Ramda and Ramda Fantasy (implementing Fantasy Land containers: Maybe, Either, Future) with currying, closures and composition to build pipelines of pure functions. Shows how pure functions aid refactoring, testing, memoization and parallelization; Maybe avoids null errors, Either separates success/error handling, and Future provides lazy, forkable async computation that runs only when forked. Mentions a real project adoption and teammate ramp-up in two evenings, and warns about learning curve, verbosity and allocation overhead on very large datasets.
