conosle log value undefined?`

textBox.addEventListener("keydown", (event) =>
  console.log(`You pressed "${event.key}".`),
);

textBox.addEventListener("keydown", (event) =>
  console.log(`You pressed "${event.key}".`),
);

In this case, the value of console.log(), which is undefined, is implicitly returned from the callback function.
