lo VS advent-of-code-2022

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-...

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

In particular, I'd like recommend samber/lo, this is a lodash generic tool for golang.

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?

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.

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.

nice one! you can make it even faster by creating a compile time multiplication table as i have done here, so all that happens at runtime is the bucketing of similarly aged fish, 7 multiplications + a sum

you've still got some overhead in your code, my rust solution creates a dense lookup array at runtime & takes ~200us on my 10850k. are you including file IO and printing to stdout?
