Syntax:

Object.entries(obj)

Parameter

Obj: It is an object whose enumerable property [key, value] pair are to be returned.

Return value:

This method returns an array of the given object's own enumerable property [key, value] pairs.

Edge Yes
Firefox 28

Example 1

const obj = { 10: 'arry', 21: 'barry', 23: 'carry' };
console.log(Object.entries(obj)[2]);

Output:

["23", "carry"]

Example 2

// creating an object constructor.
  // and assigning values to it. 
const obj = { 1: 'marrc', 2: 'sort', 3: 'carry' };
 
   // Displaying the countable property [key, value] 
   // pairs of the object using object.entries() method. 
console.log(Object.entries(obj)[2]);//access obj.

Output:

["3", "carry"]
