https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/switch - hasnt it had this forever? Or are you refering to something else?
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.

Pretty sure they meant
matchas in pattern matching, notswitchas in switch/case/break.You can see the proposal here: https://github.com/tc39/proposal-pattern-matching
Your probably right, that looks quite desirable.
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.Match already returns the value which can be thrown into a variable.
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.
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"; }Aha, yeah, I see it now. Looking forward to it.
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" };
