Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- Pipe Operator (|>) For JavaScript

A generically typed pipe function in TypeScript
An easier alternative is to wrap the value into an array, then use .map for each function in the chain, and finally escape the value with [0]
I made a similar data structure to allow adding side effect (no return value) as part of the chained function.

Tacit Programming
JavaScript is great for point-free programming! Make sure you check out Ramda.js https://ramdajs.com/
It’s fun in the sense that solving a puzzle is fun, but I avoid it for anything I need to maintain long-term.
But it’s good practice for understanding combinators which is useful for some kinds of problems.

Pipeline-Oriented Programming [video]
This is very cool. I remember I got sucked into things like Ramda going down this functional programming rabbit hole :-)

Level up your Typescript game, functionally - Part 2
To create our pipeline, I'm going to use the pipe function from the NodeJS ramda library instead of building my own.

FP and JavaScript/TypeScript
I recently took ownership of the new types/ramda repo. This repo is re-exported by @types/ramda and is the first step to bringing type definitions for ramda in-house. We're already hard at work correcting major issues, adding full currying support, and general bug fixes

When to use currying in JavaScript
I'm going to be honest. You probably don't need to use currying in JavaScript. In fact, trying to fit it in your code is going to do more harm than good, unless it's just for fun. Currying only becomes useful when you fully embrace functional programming, which, in JavaScript, means using a library like Ramda instead of the standard built-in functions.

No Lodash
Lodash gets so many things wrong I’d rather not see it in most projects. I appreciate a good utility library for JS projects but my go-to choice has to be Ramda[1]. Every function it exports is curried and works great with pipe which enables me to write highly reusable and composable functions in pointfree notation. I have never been as productive with lodash, and I find the functional style easier to read

Snap.js - A competitor to Lodash
Do note though that ramda is different from rambda. 👍 (Granted they are very similar!)
What are some alternatives?
froebel - A strictly typed utility library.
lodash - A modern JavaScript utility library delivering modularity, performance, & extras.
TypeScript - TypeScript is a superset of JavaScript that compiles to clean JavaScript output.
Rambda - Faster and smaller alternative to Ramda
remeda - A utility library for JavaScript and TypeScript.
RxJS
ramdaP-ts - TypeScript ramda utility functions for dealing with Promises (and a few misc others)
immutable-js - Immutable persistent data collections for Javascript which increase efficiency and simplicity.
IxJS - The Interactive Extensions for JavaScript
fp-ts - Functional programming in TypeScript
proposal-pipeline-operator - A proposal for adding a useful pipe operator to JavaScript.
lazy.js - Like Underscore, but lazier
