Haskell composition (.) vs F#'s pipe forward operator (|>)
...e appears on the left (see here).
(Personally, I find points-free style unreadable, but I suppose every new/different thing seems unreadable until you become accustomed to it.)
I think both are potentially viable in either language, and history/culture/accident may define why each community settle...
Does functional programming replace GoF design patterns?
Since I started learning F# and OCaml last year, I've read a huge number of articles which insist that design patterns (especially in Java) are workarounds for the missing features in imperative languages. One article I found makes a fairly strong claim :

What are some popular naming conventions for Unit Tests? [closed]
..., who the hell cares? Only you and your team will see it, so long as it is readable, and clear about what the test is doing, carry on! :)

What is the difference between cout, cerr, clog of iostream header in c++? When to use which one?
...

Convert JSON string to dict using Python
...ke the vague nomenclature used. Here is what I wrote to combat this: def read_json(json_data): if (type(json_data) == str): return json.loads(json_data) elif (str(type(json_data)) == "<class '_io.TextIOWrapper'>"): return json.load(json_data) I'm sure this can be im...
