== Why is this an issue? If the class declaration does not include a constructor, one is automatically created, so there is no need to provide an empty constructor, or one that just delegates to the parent class. [source,javascript,diff-id=1,diff-type=noncompliant] ---- class Foo { constructor() {} // Noncompliant, empty } class Bar extends Foo { constructor(params) { // Noncompliant: just delegates to the parent super(params); } } ---- Instead, you can safely remove the empty constructor without affecting the functionality. [source,javascript,diff-id=1,diff-type=compliant] ---- class Foo {} class Bar extends Foo {} ---- == Resources === Documentation * MDN web docs - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/constructor[constructor]
