#Rule Details

Disallow unnecessary constructors.

ES2015 provides a default class constructor if one is not specified. As such, it is unnecessary to provide an empty constructor or one that simply delegates into its parent class.

Examples of incorrect code for this rule:

class A {
  constructor() {}
}

class B extends A {
  constructor(...args) {
    super(...args);
  }
}

Examples of correct code for this rule:

class A {}

class B {
  constructor() {
    doSomething();
  }
}

class C extends A {
  constructor() {
    super('foo');
  }
}

class D extends A {
  constructor() {
    super();
    doSomething();
  }
}
