JavaScript Object values() Method

Q: What are some common use cases for values()?

Some common use cases include:Extracting values from an object for iteration or manipulation.Converting an object into an array of its values for easier processing.Using object values in functional programming paradigms such as map, filter, and reduce.

JavaScript object.values() method is used to return an array whose elements are the enumerable property values found on the object. The ordering of the properties is the same as that given by the object manually if a loop is applied to the properties.

Object.values() takes the object as an argument of which the enumerable property values are to be returned and returns an array containing all the enumerable property values of the given object.

Syntax:

Object.values(obj);

Parameters:

obj: It is the object whose enumerable property values are to be returned.

Return Value:

Returns an array containing all the enumerable property values of the given object.

Example 1: In this example, an array “check” has three property values [‘x’, ‘y’, ‘z’] and the object.values() method returns the enumerable property values of this array. The ordering of the properties is the same as that given by the object manually.

javascript

// Returning enumerable property values of a simple array 
let check = ['x', 'y', 'z'];
console.log(Object.values(check));

Output:

Array ["x", "y", "z"]

Example 2: In this example, an array-like object “check” has three property values { 0: ’23’, 1: ‘geeksforgeeks’, 2: ‘true’ } and the object.values() method returns the enumerable property values of this array. The ordering of the properties is the same as that given by the object manually.

javascript

// Returning enumerable property values
// of an array like object. 
let object = { 0: '23', 1: 'geeksforgeeks', 2: 'true' };
console.log(Object.values(object))

Output:

Array ["23", "geeksforgeeks", "true"]

Example 3: In this example, an array-like object “check” has three property values { 70: ‘x’, 21: ‘y’, 35: ‘z’ } in random ordering and the object.values() method returns the enumerable property values of this array in the ascending order of the value of indices.

javascript

// Returning enumerable property values
// of an array like object. 
let object = { 70: 'x', 21: 'y', 35: 'z' };
console.log(Object.values(object));

Output:

 Array ["y", "z", "x"]

Applications:

Object.values() is used for returning enumerable property values of a simple array, array-like object, and array-like object with random key ordering.

Exceptions:

It causes a TypeError if the argument passed is not an object.
If an object is not passed as an argument to the method, then it persuades it and treats it as an object.
