“Can you confirm if this syntax is correct for defining methods in Vue.js?”

When defining methods in my Vue app, I have chosen to use the following format:

methods: {
  myMethod(arg) {
    // do something here
  }
}

Although it is more common to see it written like this:

methods: {
  myMethod: function (arg) {
    // do something here
  }
}

The way I prefer may appear cleaner to me, and both methods work fine. However, could I potentially be making a grave JavaScript mistake? Could this decision come back to haunt me in the future?
