Also trying to reference self inside the prototype does not work, use this

function Person(name){
    this.name = name
}

Person.prototype = {
    openConnection : function(host, port){
        this.pointCount = 0
        this.ws = new WebSocket("ws://" + host + ":" + port)
        this.ws.onopen = this.onOpenConnection.bind(this)
    },
    constructor: Person,    
    onOpenConnection : function()   {
        console.log(this) // prints the person
        this.ws.send(this.name) // works only if one person exists
    }
}
