Get key and value of a JavaScript array into variable

Question

I have a JavaScript object array. When write console.log(myarry) it will show in the console in the below form.

Array[2]
0: Object
one: \"one\"         


        

Answer 1

• Use for-loop instead of for-in to iterate array.

• Use Object.keys to get keys of object

var arr = [{
  one: 'one'
}, {
  two: 'two'
}];

for (var i = 0, l = arr.length; i < l; i++) {
  var keys = Object.keys(arr[i]);
  for (var j = 0, k = keys.length; j < k; j++) {
    console.log("Key:" + keys[j] + "  Value:" + arr[i][keys[j]]);
  }
}
