Refactor reflect.DeepEqual to slices.Equal from the standard lib

[konsalex]

Hey folks,

Would it make sense to add also the new way to compare slices in this chapter: https://quii.gitbook.io/learn-go-with-tests/go-fundamentals/arrays-and-slices#write-enough-code-to-make-it-pass-4

So instead of using reflect.DeepEqual to use slices.Equal.

I could make a contribution to add this

The guide does mention slices.Equal here:

learn-go-with-tests/arrays-and-slices.md

Line 341 in 0619712

(From Go 1.21, [slices](https://pkg.go.dev/slices#pkg-overview) standard package is available, which has [slices.Equal](https://pkg.go.dev/slices#Equal) function to do a simple shallow compare on slices, where you don't need to worry about the types like the above case. Note that this function expects the elements to be [comparable](https://pkg.go.dev/builtin#comparable). So, it can't be applied to slices with non-comparable elements like 2D slices.)

And go 1.21 has been out for a while: https://go.dev/doc/devel/release#go1.21.0

So I think it could make sense 🤔

but I am not sure, maybe the guide tries to make zero assumptions on the go version being used? 🤷

late reply, but if you're still willing, go for it!

Will do with the first chance!
