the problem is with heading.value You want text to be in between the tags. So use heading.textContent or heading.innerText heading.value will look for value attribute which heading doesn't have.

class Myheading extends Heading { constructor (value,color) { super (value); this.value = value; this.color = color; } value () { return this.value ; } color () { return this.color ; } In this code you don't have to explicitly define value() method and this.value property. super(value) will do it for you. class Myheading extends Heading { constructor (value,color) { super (value); this.color = color; } color () { return this.color ; } This will also work
