Lost this Binding in Timer Callback

A regular function passed to setInterval loses its this binding inside an object method.

Codejavascript

const timer = {
  seconds: 0,
  start() {
    setInterval(function () {
      this.seconds++;
      console.log(this.seconds);
    }, 1000);
  }
};

timer.start();
