how ternary operator works code example

Example 1: ternary operator

// (condition) ? (if true, do this) : (otherwise, do this)
const hasAccount = true
// let userDisplayMessage
// if (hasAccount) {
//   userDisplayMessage = 'Welcome Back'
// } else {
//   userDisplayMessage = 'Please Sign Up'
// }
const userDisplayMessage = hasAccount ? 'Welcome Back' : 'Please Sign Up'
console.log(userDisplayMessage)

Example 2: Ternary Operator

condition ? expression-if-true : expression-if-false;

function findGreater(a, b) {
  return a > b ? "a is greater" : "b is greater";
}
