Question

What's the output?

function getAge(...args) {
  console.log(typeof args);
}

getAge(21);

• A: "number"
• B: "array"
• C: "object"
• D: "NaN"

Answer 1

Answer: C

The rest parameter (...args) lets us "collect" all remaining arguments into an array. An array is an object, so typeof args returns "object"
