And the best:
public static void () {}
- Technically java would also be (){} since the modifiers are optional (outside of public static void main(String... args)) and return type is ignore for the others :D
  
  Yeah, it's a joke, but I disagree on the void, the other languages on the meme doesn't need a return type (when they are returning nothing), java needs it.
  
  Yeah the thing is that each part of "public static void" is a feature. Which other languages don't have.
  Still makes a good meme for programmers who are not experienced enough to know that.
:(){:|: &};:
- bash
  
  :(){:|: &};: :(){:|: &};:
  
  :(){:|: &};: :(){:|: &};: :(){:|: &};: :(){:|: &};:
Bash fucks me up so much, too. You just put the parentheses there to say that something is a function, not for actually declaring the parameters that can be passed in...
- This really sends me
- |{}
Haskell: =
- The language of the gods
javascript

function() {}
- JavaScript can do better than that:
  javascript
  
  () => {}
  
  C++: [](){}
  
  The intention was to provide a longer version for the first step of the ladder.
Some Lisp dialects: (λ () )
- your IDE is hiding 6 characters there
  
  Some Lisps will accept a literal Unicode lambda character.
They could have put php up the top where it belongs.

Idk much about programming but that looks like a beautiful reduction of bloat in coding language 😶
kotlin also has ()->{} and {} (when there is just 1 parameter)
I don't use any but I'm sure there are functional languages where () is a function.
- In Haskell, that's "unit" or the empty tuple. It's basically an object with no contents, behavior, or particular meaning, useful for representing "nothing". It's a solid thing that is never a surprise, unlike undefined or other languages' nulls, which are holes in the language or errors waiting to happen.
  You might argue that it's a value and not a function, but Haskell doesn't really differentiate the two anyway:
  
  value :: String value = "I'm always this string!" funkyFunc :: String -> String funkyFunc name = "Rock on, "++name++", rock on!"
  Is value a value, or is it a function that takes no arguments? There's not really a difference, Haskell handles them both the same way: by lazily replacing anything matching the pattern on the left side of the equation with the right side of the equation at runtime.
  
  Mostly a great comment, but I wouldn't compare unit to null, it's more like the void type.
