新手尝试构建Javascript年龄计算器

Question

I'm a new self-learner and have recently taken on javascript. I have an assignment (from an online code camp) that I just cant seem to make pass. I feel like I understand the basics of it, but I can't write it in a functional way. Can anyone help me here?

The question is in the attached image.

My code looks a little something like:

function ageCalculator(name, yearOfBirth, currentYear) {
  var age = currentYear - yearOfBirth;
  return (name + "is" + age + "years old.");
  console.log(ageCalculator("Miranda", 1983, 2015));
}

I would appreciate any help! Thank you!

Answer 1

You're calling the function ageCalculator just after the return statement. Anything just after the return statement won't be called.

Just pull that call outside.

 function ageCalculator(name, yearOfBirth, currentYear) { var age = currentYear - yearOfBirth; return (name + " is " + age + " years old."); } console.log(ageCalculator("Miranda", 1983, 2015)); 

Answer 2

Call the function outside the function declaration.

 function ageCalculator(name, yearOfBirth, currentYear) { var age = currentYear - yearOfBirth; return (name + " is " + age + " years old."); } console.log(ageCalculator("Miranda", 1983, 2015)); 

Answer 3

Whenever you return , the function stops immediately: it'll never get to your console.log the way it is now. Call console.log and the function itself outside your function, you don't want an infinite recursive loop.

Also make sure to add proper spacing:

 function ageCalculator(name, yearOfBirth, currentYear) { var age = currentYear - yearOfBirth; return (name + " is " + age + " years old."); } console.log(ageCalculator("Miranda", 1983, 2015));
