  • bind

     
    a.execute = function () {
      let bound1 = this.callback1.bind(this);
      let bound2 = this.callback2.bind(this);
        
      bound1();
      bound2();
    }
    a.execute();

  • arrow

     
    a.execute = function () {
      let bound1 = () => this.callback1();
      let bound2 = () => this.callback2();
        
      bound1();
