How to $watch multiple variables?

Question

I do have two $scope variables. They are called $scope.image and $scope.titleimage.

Basically the store the same type of contents.

Answer 1

Use computed and return multiple variables in an array that you want to listen to that should execute the same function.

computed: {
  photo () {
    return [this.image, this.title]
  }
},
watch: {
  photo () {
    console.log('changed')
  }
},
