How to check the change of an Array in JS

Question

I have an object array and want to perform a function when it changes its value (adding or removing the items). I’m using the md-checkbox of Angularjs with the checklist-model to include values within my array.

Example:

  var vetor = [
    {
      id: 1,
      nome: 'maça'
    },
    {
      id: 2,
      nome: 'laranja'
    },
    {
      id: 3,
      nome: 'banana'
    }
  ];

  alterouValor() {
    // minha função
  }

So from there, any value that adds or removes should also call the function alterouValor.
