<input type="radio" id="gender0" name="gender" value="Male" />Male<br />
<input type="radio" id="gender1" name="gender" value="Female" />Female<br />
to add radio buttons.

const gender = document.querySelector('input[name = "gender"]:checked').value;
to select the selected radio button with name attribute gender with querySelector.
