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.

Go 1.18 Released
Im not sure about any library in particular.
There were bunch of libraries which helped with code generation to work around generics. I don't think it was specific to Graphql.
https://github.com/cheekybits/genny is one I have seen.

To Those Who Criticize JavaScript
TypeScript is pretty much necessary for a modern JS project if you ask me, so I agree with you here. At the same time, I'd say that if the JS ecosystem offers a solution, that doesn't count as a failure. It's like pointing to the lack of generics in Go and calling that a failure. No, that's a design choice that can be worked around. Same in JS; dynamic typing was a design choice, TypeScript is a solution.

Learn to build SDK or Wrapper over REST and Websocker
If you want to experiment, I've been meaning to try out this library, which uses code generation (a first-class feature in go), to give generics-like functionality.

Created my first go tool, an interface generator
If you are into codegen, there are some larger codegen projects or there, like cheekybits/codegen (there are more in the space of trying to circumvent generics in go).

Metaprogramming
In golang there is no parametric polymorphism (or “type parameters”, or “generics”). So people created workarounds, for example, gengen (similar solutions genny, generic, gen):
