I often have the pleasure of refactoring this mess. And sometimes it’s not just 2 ternaries but like 4 or 5 thrown together. It took like half an hour to even understand what was going on. If you do this, you are just an evil person…
So I totally support this. Stop this shit…

This shit always leaves me wondering who even writes this crap. The answer is more often than not a junior that just discovered code golf thinking he’s oh so clever. You learn to appreciate boring code, with experience…
- kassuro ( @kassuro@feddit.de ) 4•10 months ago
Totally agree with you. I’m always an advocate for boring and easy to understand code.
I really don’t need an extra layer of complexity just so someone can save a line or two.

If you can use any of the jetBrains IDE it can rewrite it to if/else with a few clicks (or [alt] +[return])
- kassuro ( @kassuro@feddit.de ) 2•10 months ago
Ah that would be helpful. Gotta try that the next time I encounter such a monstrosity.

Until JS supports switch expressions, nested ternaries will continue to be the most effective way to write multi-state conditionals.
Also, stop using linting tools that prioritize consistency over human readability, and then complaining that the code they generate is not easily-readable by humans.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/switch - hasnt it had this forever? Or are you refering to something else?
- spartanatreyu ( @spartanatreyu@programming.dev ) 10•10 months ago
Pretty sure they meant
match
as in pattern matching, notswitch
as in switch/case/break.You can see the proposal here: https://github.com/tc39/proposal-pattern-matching
- CameronDev ( @CameronDev@programming.dev ) 3•10 months ago
Your probably right, that looks quite desirable.
- snowe ( @snowe@programming.dev ) 2•10 months ago
they also said switch
expressions
, which indicates they want the switch statement to be settable directly to a variable with whatever the return type of the switch is.- spartanatreyu ( @spartanatreyu@programming.dev ) 2•10 months ago
Match already returns the value which can be thrown into a variable.
- JakenVeina ( @JakenVeina@lemm.ee ) 1•10 months ago
Nah, I meant switch, as that’s what it’s called in C#-land. See above.
That proposal for matching looks interesting, but not quite the same, no.
- spartanatreyu ( @spartanatreyu@programming.dev ) 4•10 months ago
Are you sure?
Your C# example:
var output = input switch { null => "Null", 0 => "Zero", > 0 => "Positive", _ => "Negative" };
JS proposal for match:
const output = match input { when null: "Null"; when 0: "Zero"; if input > 0: "Positive"; default: "Negative"; }
- JakenVeina ( @JakenVeina@lemm.ee ) 1•10 months ago
Aha, yeah, I see it now. Looking forward to it.
- JakenVeina ( @JakenVeina@lemm.ee ) 2•10 months ago
Yeah, a switch expression is different than a switch statement. I’m not actually sure how many languages actually have them, but in C# its…
var output = input switch { null => "Null", 0 => "Zero", > 0 => "Positive", _ => "Negative" };

Does this article need to exist? I assumed anyone writing a nested ternary was intentionally writing shit code
- T (they/she) ( @Templa@beehaw.org ) 6•10 months ago
Some people think they are being “cleaver” writing a lot of stuff in one line. So yes, it does.

No.

I’ll be sending this article to my dev teams. It’s right up there with “stop writing Helper classes”.
- coloredgrayscale ( @coloredgrayscale@programming.dev ) 5•10 months ago
What’s wrong with helper/util classes?

Or anywhere for that matter. Have you got nested IF()s in Excel? For crying out loud, pop into VBA and write it up as a custom function like a human being.
- spartanatreyu ( @spartanatreyu@programming.dev ) 4•10 months ago
Good news Everyone
Excel has a JS API now, so we can get rid of VBA entirely and fill Excel with terrible ternary operators!
- jadero ( @jadero@programming.dev ) 1•10 months ago
Oh, I didn’t know that Excel could do JS. I haven’t touched it since I got out of the field a decade or so ago.
One of the things I did was quite a bit of Excel consulting and training. I remember the joy of trying to decode massive formula cells, especially when there were nested IF()s. My rule of thumb was that anything with more than three functions in one formula got converted to a custom function, even if it didn’t have general utility.
I found that anyone who could construct and understand those massive formulas were generally capable of dealing with the equivalent VBA with a bit of training. Also, it was generally true that if they couldn’t handle the relevant VBA, they were in no position to deal with massive formulas anyway.
