<p>JSON.stringify will not stringify functions.</p>
<p>You have to convert functions to strings first:</p>
​
<p id="demo"></p>
​
<script>
const person = {
  name: "John",
  age: function () {return 30;}
};
person.age = person.age.toString();
​
document.getElementById("demo").innerHTML = JSON.stringify(person);
</script>
