How to correctly call a class method in the SetInterval function?

Question

Node.js

class Server{
 constructor(){
   this. arrayGame = []
}

Update(){
   for (let i =0; i < this.arrayGame.length; ++i){
    что то происходит
  }
}
}

I need to call the Update method every second, tell me how to call it correctly?

Answer 1

I don't know the syntax of ES6 classes, but it seems like this

class Server{
 constructor(){
   this.arrayGame = []
   var self = this;
   setInterval(function () { self.Update() }, 1000);
 }

Update(){
   for (let i =0; i < this.arrayGame.length; ++i){
    что то происходит
  }
}
}
