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.

Why doesn't go have Ternary?
No everything is lost, if it is really necessary there are packages in Go that create the ternaries in Go or leave it very close to what we have in other languages, example: ternary, logically we must have other scattered around Github.
- None of you asked for it and I wouldn't have listened anyways: Ternary syntax now available in Go!

Go 1.22 Release Notes
> can't wait for some map/filter/find slice functions though
Till that day comes, you could use the "lo" library (inspired from lodash). It's my goto Swiss army knife for golang projects.
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-...
- 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.
