TypeScript complain “has no initializer and is not definitely assigned in the constructor” about constructors by returning constructed object

Question

TypeScript show following error message to this code samples:

class MyClass {
  someField: boolean;
  constructor() {
    return { someField: true };
  }
}
         


        

Answer 1

It considers {someField: true} as new object and the property someField has not been initialized.What is the purpose of return inside the constructor? You can replace it with this.someField = true.

Edit: Actually, I debugged for more info, Try adding "strictPropertyInitialization": false to your compiler options and check. But it overrules the type strictness(beautiful feature of TS). But In my opinion, do not do this. For more info.
