You can also use Spread Operator

or for loop

const names = ['Alex', 'Bob', 'Johny', 'Atta'];


const obj = {};


for (let i = 0; i < names.length; i++) {
    obj[i] = names[i];
}

Create object from Keys and Values with 2 arrays

Not recommended iterate values and keys at the same time.

<script>

    var keys = ['key1', 'key2', 'key3'];
    var values = [
    [12,112, 1112],
    [31, 331, 3331],
    [64, 653, 6621]
    ];

    var arrayOfObjects = [];
    for(var i=0; i<values.length; i++){
      var obj = {};
      for(var j=0; j<values[i].length; j++){
       obj[keys[j]] = values[i][j];  
     }
     arrayOfObjects.push(obj);
   }

   console.log(arrayOfObjects)

</script>

Output:

0: Object { key1: 12, key2: 112, key3: 1112 }
​
1: Object { key1: 31, key2: 331, key3: 3331 }
​
