What's New in JavaScript for 2019

Re:What's New in JavaScript for 2019 by Lerc on Tuesday January 22, 2019 @04:21PM (#18972603)

Ok reading that I'm going to amend my suggestion above.

    class fish {
     color = "blue";     // color is now a name in scope for this class definition
     #agenda = "Total World Domination"  // agenda is now a name in scope for this class definition

    ...
     reveal () {
       console.log("I am a " 
               + color + " Fish "  // interpreted as this.color
               +"seeking " + agenda // interpreted as this.#agenda;
     }
    }

You can still have this.agenda for public addon fields. But for the private one you can refer to it within the class definition without either this. or #

Yes please make the syntax simple like this! Even cleaner:

  class fish {
     color = "blue";    
     private agenda = "World Peace"  
     constructor(){
           color="red"
           agenda="Secret World Domination"
     }
     reveal () {
       console.log(`I am a ${color} Fish seeking ${agenda}`)
     }
    }
