The JavaScript Object.entries function serves to produce an array consisting of an object's own enumerable property [key, value] pairs. The sequence of these properties corresponds to the order in which one would traverse the property values of the object in a manual iteration.
Syntax:
Example
Object.entries(obj)
Parameter
Obj: It refers to an object that is intended to return its enumerable properties as [key, value] pairs.
Return value:
This approach yields an array consisting of the object's own enumerable property [key, value] pairs.

Example 1
Example
const obj = { 10: 'arry', 21: 'barry', 23: 'carry' };
console.log(Object.entries(obj)[2]);
Output:
Output
["23", "carry"]
Example 2
Example
// 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:
Output
["3", "carry"]
Example 3
Example
// creating an object constructor.
// and assigning values to it.
const obj2 = { 10: 'arvind', 2: 'rahul', 7: 'Ankit' };
// Displaying the countable property [key, value]
// pairs of the object using object.entries() method.
console.log(Object.entries(obj2)[2]);
Output:
Output
["10", "arvind"]
