+// Explanation:
 function sum(a, b) {
   return;
   a + b;
+  // =============> write your explanation here
+  // The `return;` statement ends the function early, so `a + b` is never reached.
+  // In JavaScript, any code after a bare `return;` is ignored (unreachable code).
+  // That's why the function returns `undefined`, not the actual sum.
