How do I change a variable based on radio input

Question

As you can see in the attached code, I’ve already succeeded in making a name and age variable which changes depending on what you type/input.

What I now need is to make the gender variable become either male or female depending on which radio button you click.

If you know how to, I would be so grateful for your help!!

Answer 1

let gender = document.querySelector('input[name="gender"]:checked').value;

And remember to set the value-attribute of the radio buttons.

Answer 2

let gender = document.getElementsByName("gender")[0].value
