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.

Go 1.18 Released
>> By introducing a single generic, you could reduce it from 500 lines to 20
No one is writing 500 lines of code - just as when you use the generics syntax you don’t write the code that is generated by the compiler in response.
You could save about 10 lines, specifically these 10:
https://github.com/logic-building/functional-go/blob/master/...
You would still need the comparable ~40 lines of “generic” code:
https://github.com/logic-building/functional-go/blob/master/...
-
Do you see any interesting use cases for the upcoming type sets, other than generic type constraints?
Yes! There is this library that uses go generate for achieving functional patterns https://github.com/logic-building/functional-go. It would really benefit from such thing.

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.
- Khan Academy's switch from a Python 2 monolith to a services-oriented backend written in Go.
-
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.
-
samber/lo utility package based on generics
I came across samber/log a package based on generics for providing utility methods.
What are some alternatives?
