  <pre><code>let a = [
      { id: 1, activated: '0' },
      { id: 2, activated: '0' },
      { id: 3, activated: '0' },

    ]
  let b = [
      { id: 2, activated: '1' },
      { id: 3, activated: '1' },
    ]
  //Result array:
  c = [ 
    { id: 1, activated: '0' },
    { id: 2, activated: '1' },
    { id: 3, activated: '1' },
    { id: 4, activated: '0' },
