No need to start with 400+ pages books. The domain name could be better (more prominent) though.

Looks like a nice book indeed. My only issue is that it has 336 pages so it is quite a bit to take in. I think F# basics can be explained in a fraction of that, just to get people started.

Learning F# (or any technology really) is so much easier now thanks to ChatGPT. My tip is to be careful with F# for fun and profit. While interesting it also has lots of parts which are not really useful. What’s missing is a more approachable, simple, F# for C# devs tutorial.

From an outside perspective it didn’t look like the last minute democratic nominee was a particularly good choice.

Type classes separate structure from behaviour. In F# we can easily customise behaviour in many ways. Easiest is to pass a function, other ways are more involved (function dictionaries, interfaces). Scala devs can customise ToString implementations on a case-by-case basis. Just as we can 👍🏻

Computation expressions to the rescue (what an invention!). Check out this slick implementation: github.com/brianrourkeb...
This one should not go under the radar 💪🏻

Most of my files are around 100 lines, many less than that. Some reach 400 lines. Not concerned too much as I trust the language when refactoring. What I struggle with sometimes is where to place types. Sometimes I wish F# supported tree structured module dependencies to reduce type visibility.

Hi Seegey, your fine blog keeps asking me this every I want to read your latest post.

Wow that is a lot to take in! I’ve got a few workers I’ve (somewhat painfully) implemented in JavaScript. This opens up an entirely new front!

Both have strengths and weaknesses (yes F# too has weaknesses, in particular harder to understand). I don’t like dotnet in-fighting. If you’re only doing F# or C# you’re missing out (IMHO). They could have compared C#/F# combo with Java instead.

It’s interesting that monads keep coming up around F#. I can only find it mentioned in one of the official pages on F# (on CE naturally, but only in passing).

I guess it is due to C legacy: first saying what it is, then its name. Just typing in that order immediately invokes imperative mindset (I want memory of this type). Type after matches how variables are declared in math. It’s like a structure applied on top of my variables

A language designer can probably explain better, but to me ”Type t” feels imperative, while ”t : Type” feels declarative. Unified syntax and optional parenthesis would be nice to have in C# 😊

I do some programming in F#. Here’s what I regularly use:
- computation expressions: Yes
- Railways: Rarely…
- Partial application and currying: Rarely
- Monads: Implicitly through CE’s
- Discriminated unions: All the time
- Pattern matching: Yes!
- Type-safe programming: Yes, straight from db!
- computation expressions: Yes
- Railways: Rarely…

Nice example. Only issue with pipelining is that sometimes we want to inspect intermediate results. This requires modifying the pipeline while it comes naturally in the other one.

It has been working fine for smaller greenfield projects. I got a lot of help with some complex functions. For my larger projects I find it less appealing.
