  5. remeda

    A utility library for JavaScript and TypeScript.

    Project mention: dot-into, pipes in TypeScript | dev.to | 2026-04-05

    I honestly do not love working with JS or even TS, but when I do, I like having something akin to a |> pipe operator available, common in functional programming such as the ML family of languages and Elixir. I'd much rather use a library of nice, functional utility functions that can operate on various forms of plain data (such as the TS-native Remeda) than dealing with objects with state and members and so on.
