ES6: Accessing Variable Classes from within a Method with _this_

It turned out that the problem was in the context of using the method log()

:

export default class myClass{
    constructor () {
        this.logCount = 0
    }

    openSocket() {
        let mySocket = new WebSocket('wss:/.../...')
        // wrong: because you loose the this-context
        // mySocket.onopen= this.log
        // correct:
        mySocket.onopen= ((evt) => {this.log(evt)})
    }

    log (msg) {
        this.logCount++
        console.log(this.logCount + " - " + msg)
    }
}

      

        
        
        
      

    

Thanks everyone for your help and suggestions!
