What is the difference between class methods, why is this - window?

  We have a class:
  

  class Cls {
    constructor({
      outside
    }) {
      this.outside = outside;
    }
    
    inside = () => {
      console.log('inside', this);
    };
  }

  
  
  create instance. in the parameters of which we pass an object with an arrow function:
  

  const outside = () => {
    console.log('outside', this);
  };
  
  const instance = new Cls({
    outside
  });

  
  
  call 2 methods
  

  instance.inside();         // "inside" instance
  instance.outside();      // "outside" window

  
  
  Moreover, the methods in instance, except for console.log, are no different.

  They differ in the context in which they are declared. They have this different.
