A better case statement?

case.js

// Prettier case statement, but can also return a value since it is an expression.
//

first_condition
  ? first_action()
: second_condition
  ? function() {
    var local_var = 'whatever'
    second_action(local_var)
    return whatever_else({you: "want"})
    }()
: third_condition && can && (be || compound)
  ? ( can()
    , abuse()
    , commas()
    , console.log("For fun")
    )
  : default_action()
