Exercism - Scala Exercises VS hoogle

You could do some problem solving with leetcode, codewars, or exercism.

exercism.org is another, very beginner friendly site for this.

Also, you can check out exercism.org. It's a learning platform. And it's free!

Try looking at https://exercism.org. They have tons of exercises to try out.

https://exercism.org maybe?

Some resources: - devdocs.io - codewars - exercism - leetcode - free python books

Exercism is a blend of lessons, practice, mentoring, and community surrounding dozens of different programming languages.

I highly recommend you take the courses at https://exercism.org on c#. They are intuitive and you can likely find a mentor to help you grow longer term.

https://exercism.org/ can be a rewarding place to give mentoring

Ideally like this: https://zio.dev/reference/#concurrency

Or this: https://hoogle.haskell.org/?hoogle=fork

{ "customLocalFormatters.formatters": [ { "command": "make format", "languages": ["haskell"] } ], "emeraldwalk.runonsave": { "commands": [ { "match": "*.hs", "isAsync": true, "cmd": "make retag retag_file=${file}" } ] }, "ghcid.command": "make ghcid", "goto-documentation.customDocs": { "hs": "https://hoogle.haskell.org/?hoogle=${query}" } }

You had a look at Hoogle?

https://hoogle.haskell.org/

For some type signatures there is (are) only one (or only a few) meaningful implementation(s).

I'm in the middle on operators. I like being able to define my own, but I understand how it's challenging to figure out what the hieroglyphics mean when you're not familiar with them. https://hoogle.haskell.org/ can be a help here

> In something like Haskell I need to know upfront what I may do with some "object". The IDE can't help me discover the methods I need. All it can do is to show me all available functions in scope.

Sorry, but this just isn't true. Hoogle <https://hoogle.haskell.org/> searches function by type, fuzzily: ask for functions whose first parameter is the type of the object-like thing, and you'll get just what you're looking for. And it's perfectly possible to run hoogle locally and integrate it with your editor.

Now, the tooling for a language like Java have had several centuries more of aggregate development work done on them compared to Haskell's tools, and if that polish is a difference-maker for you, that's fine! But it's not a fundamental limitation, and claiming it is is just fud.

In my perusals into the Haskell ecosystem, discovering Hoogle[1] was definitely a revelation on the power of a strongly-typed language. Sometimes, you know the _shape_ of the thing you are looking for, but not the name. The ability to search a repository of packages for all functions conforming to a certain type signature (e.g., (a -> Bool) -> [a] -> [a]) is a superpower.

which is quite a bit more readable. You can even search Hoogle for x -> HashMap x y -> y and find it, try it!

Haskell has hoogle, which searches Hackage for functions matching names, type signatures, etc.

Hello, I am wondering if there is something like https://hoogle.haskell.org for the rust language.
