How is it compared to JetBrains' https://hyperskill.org ? They seems to be competitive products.
PS. HyperSkill's pricing is also more competitive. They offer tons of tracks containing hundreds of coding projects at the price of 240$ per year, while CodeCrafers' charge is 790$ per year.
We last looked at JetBrains academy ~6 months ago and at the time it mostly had beginner-level content. Looks like they've got some advanced content now, like this one: https://hyperskill.org/projects/112?track=2.
I'd consider them a competitor, and I like their approach - hands-on project-based learning with automated tests to guide your implementation.
I think the primary difference (aside from their content being slightly skewed towards beginners and the limited languages on offer) is that our format involves re-creating devtools from scratch.
This article should be written with Rust/Haskell/Scala/OCaml/TypeScript ... or any languages with an insane type system. Anyway it can’t be Go, a language without sum type.
