How can I make two dimensional array with JSON objects into single array in javascript?

Question

Here i have a JSON object in an array and have it pushed to employeeArray which is

employeeArray =[  
  [  
    {  
      "ID":"967",
      "NAME":"Dang, Lance D",
      "Email":"[email protected]"
    }
  ],
  [  
    {  
      "ID":"450",
      "NAME":"Starnes, Mitch",
      "Email":"[email protected]"
    }
  ],
  [  
    {  
      "ID":"499",
      "NAME":"Cosby, Lance H",
      "Email":"[email protected]"
    }
  ]
];

How do i get this into a single array with JSON objects like this

employeeArray =[  
  {  
    "ID":"967",
    "NAME":"Dang, Lance D",
    "Email":"[email protected]"
  },
  {  
    "ID":"450",
    "NAME":"Starnes, Mitch",
    "Email":"[email protected]"
  },
  {  
    "ID":"499",
    "NAME":"Cosby, Lance H",
    "Email":"[email protected]"
  }
];

help me how to use above two dimensional array values and build my expected array in pure javascript

Start by learning, for example, try googling "what is json" & "javascript array". Then think about what got you into this state you're trying to get out of. — Amit

You want to flatten the array, which can be done with a reduce call:

employeeArray.reduce((p, c) => p.concat(c), [])

ES5:

employeeArray.reduce(function (p, c) {
  return p.concat(c);
}, []);
