Example + Live Practice

<script>
  // Arithmetic and comparison
  const a = 10;
  const b = "5";
  const total = a + Number(b);
  const status = total > 12 ? "Greater" : "Smaller";

  const valid = total > 0 && total < 20;
  console.log("Total: " + total + ", Status: " + status + ", Valid: " + valid);
