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.

(Rust) Tokio, FuturesUnordered, and the Thundering Herd Problem
Only thing missing from making it look and work as traditional async is lack of pre-processor to make it "look nice". Generics do make it a bit better, for example from my lib you can introduce some concurrency quite easily, for example

Conc: Better Structured Concurrency for Go
I do like idea of waitgroup on steroids, I might steal it for my generic library.

Have yet to use generics...Am I missing out?
Shameless plug: here is a list of some useful stuff you can do with it, with code attached.

I've created a Go Generics cheatsheet to give you a quick reminder of how to use this feature
If someone wants some more examples I've made a lib with a bunch of common constructs. Fun ones include "run function in parallel on a slice and put it in output slice in order" or "return which elements are different between slices", with version allowing to easily get difference between 2 different types using conversion function
- Spawn multiple go routines, get the results back, in order of goroutine spawn...

Go 1.22 Release Notes
On the other hand, I advise you NOT to use this kind of library and write simple, fast go code most of the time, with the occasional generics helper. Why the hell would I clutter my code with, for example: https://github.com/samber/lo?tab=readme-ov-file#fromentries-...

Go is not an easy language (2021)
This wasn't feasable without generics, and now with generics they're already adding some convenience functions to the stdlib, like in the slices package.
For map, reduce etc it's not in the stdlib yet, but you can use https://pkg.go.dev/github.com/samber/lo
- I wrote a for loop so you don't have to. Parallel Map, Filter, Reduce library

What is your recommendation for a package beyond std?
In particular, I'd like recommend samber/lo, this is a lodash generic tool for golang.

What 3rd-party libraries do you use often/all the time?
What are some 3rd-party libraries for Go that you use often/all the time? Instead of "just implement everything yourself", I would really like to get some tips. For instance, a few days ago I discovered https://github.com/samber/lo , which looks very good if I want to have list comprehensions (Python) / LINQ methods (C#). https://pkg.go.dev/github.com/atotto/clipboard is also good for clipboard operations. What else do you suggest and for what task?

Functional Programming Library for Golang by IBM
A simple alternative is the combination of:
- https://github.com/samber/lo
- https://github.com/samber/mo
The split is also nice as you can choose to just use the generic convenience functions from lo without the more FP related things from mo.

In what ways are channels are better than the traditional await?
Some packages offer utilities to gather results from goroutines, such as multierror.Group or parallel.Map in samber/lo.
