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 1.22 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.

samber/lo utility package based on generics
I came across samber/log a package based on generics for providing utility methods.

Handling nil values: Pointers vs Abstractions
Is it a popular approach to use abstractions in general for handling nil values with libraries like null or mo? Should I just stick with pointers? What are your experiences on this topic?

samber/lo utility package based on generics
I really like it. Have been using it for a while, just don't overuse it. Also, I recommend github.com/samber/mo

Switching from C++ to Rust

I know there is no OPTIONALS in go , i hope they implement it , what is the best approach to deal with optionals in go? sometimes i think the default values added by golang isnβt suitable, like adding zero to int ! .. zero is a value not nil or undefined.
Have you taken a look at mo? https://github.com/samber/mo

What the state of functional programming ecosystem ?
If you are curious, try looking at github.com/samber/lo and github.com/samber/mo packages if you get a chance.

Reduce Boilerplate in Go Http Handlers with Go Generics
I have seen https://github.com/samber/mo but it's a niche. Monads aren't popular in Golang community.

Expected vs Unexpected errors in Go
I've also looked at the mo library, in particular to use Option[User] but that's really just a slightly safer way to represent User* here. (Safer because you're forced to check if there's a value and so don't have the same accidental panic risk.)
