Transformation of super calls in methods

This feature allows the transformation of super calls within methods of a class. The code sample shows a class where both the constructor and a method use 'super' to call their respective counterparts in the parent class.

class Child extends Parent {
  constructor() {
    super();
    console.log('Child constructor');
  }
  myMethod() {
    super.myMethod();
    console.log('Additional code in child method');
  }
}

Handling of super calls in constructors

This feature specifically handles the transformation of super calls within constructors, ensuring that the parent class's constructor is called before the child class's constructor logic is executed.

class Child extends Parent {
  constructor() {
    super();
    this.state = { key: 'value' };
    console.log('Child constructor');
  }
}
