if / else

code

if (age >= 18) {
  console.log("adult");
} else {
  console.log("minor");
}

Ternary

code

const label = isAdmin ? "admin" : "user";

Nur fuer einfache Faelle, sonst lieber if.

Short-circuit

code

const name = input || "guest"; // Default (aber 0/"" sind false)

Mit modernen Defaults:

code

function countToFive(start = 1) {
  for (let i = start; i <= 5; i++) console.log(i);
}

Switch

code

switch (role) {
  case "admin":
    break;
  case "user":
    break;
  default:
    break;
}
