Question

What's the output?

class Person {
  constructor(name) {
    this.name = name;
  }
}

const member = new Person('John');
console.log(typeof member);

• A: "class"
• B: "function"
• C: "object"
• D: "string"

Answer 1

Answer: C

Classes are syntactical sugar for function constructors. The equivalent of the Person class as a function constructor would be:

function Person(name) {
  this.name = name;
}

Calling a function constructor with new results in the creation of an instance of Person, typeof keyword returns "object" for an instance. typeof member returns "object".
