Is there any way to do ternary expression?

[coconParticipant]

I don’t know if “ternary operators” exist in Monkey, but you get the idea, to do boolean check and assignment in one line. I don’t know if I remember correctly, that in MonkeyX this feature was supported.

Other alternative way I found is this, which adds some unnecessary complexity.

Monkey

#Import "<std>" Using std.. Function Main() ' Self invoked lambda function. Local a := (Lambda:String() If True = True Return "It's true" Else Return "It's false" End End)() Print(a) ' More compacted syntax. Local b := (Lambda:String() If True = True Return "It's true" Else Return "It's false" End)() Print(b) End

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

#Import "<std>" Using std..   Function Main() ' Self invoked lambda function. Local a := (Lambda:String() If True = True Return "It's true" Else Return "It's false" End End)()   Print(a) ' More compacted syntax. Local b := (Lambda:String() If True = True Return "It's true" Else Return "It's false" End)() Print(b)   End

Superb!

How this actually is called in Monkey? Ternary?

[coconParticipant]

From what I see it’s called an “If Expression”

I’m not sure what’s going on behind the scenes, but I’d call it a “ternary operation” because it takes three elements and behaves like an operator.
