Super() keyword in Angular?

Question

Angular

I write code:

constructor() {
    super()
 }

I get Error: 'super' can only be referenced in a derived class.
What is the problem?

Answer 1

Apparently, the problem is that you do not understand what super() is and why it is needed. Well, inheritance in addition. Because in the text of the error everything is described quite clearly.

Answer 2

Not all code showed
https://www.typescriptlang.org/docs/handbook/class... look for a piece according to the words Inheritance extends
If the class is not inherited from another, super is not written.
