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.

1.18 is released
I already played around a bit wit the beta a while back and made an iterator library to get to know this new language. It's here for anyone interested: https://github.com/polyfloyd/go-iterator

iter: Generic, lazy iterators for Go 1.18
Regarding call chaining, it is still possible to chain things with operations that return different types, but they have to be done with functions instead of methods, so the result is still the same, just it's a little less readable. There is a generic iterator implementation by polyfloyd that doesn't support method chaining, but imo being able to chain iterators is one of their biggest strengths, since implementing lazy evaluation manually for a single operation isn't that difficult, its when you need to perform multiple kinds of manipulations that it gets messy.

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.

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

Querying and transforming object graphs in Go
However, as others have remarked, https://github.com/samber/lo is more popular recently. You can view a comparison of the two approaches in this:
If you're looking for something like LINQ in the sense that it has those functions and can strictly (as opposed to lazily) interact with structures to get those functions, there's quite a few functional libraries on pkg.go.dev. lo seems popular.
