Inheritance method call triggers Typescript compiler error

Question

I am having an issue with webstorm typescript compiler. I have the following classes

export class rootData{
  id:string
  //...

  constructor(){
    //...
         


        

Answer 1

Because super calls are redirected to the prototype you cannot use a property and need to use a method i.e. can't use = ()=>.

Fixed code:

export class rootData{
  id:string
  //...

  constructor(){
    //...
  }

  insert():Promise{
    //...
  }
}

class child extends rootData {
  //...   

  constructor(){
     super();
  }

  insert():Promise {
        return super.insert();
    }
}
