This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The Object.values() method returns an array of a given object's own enumerable property values, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

Syntax

Object.values(obj)

Parameters

obj
The object whose enumerable own property values are to be returned.

Description

Object.values() returns an array whose elements are strings corresponding to the enumerable property values found directly upon object. The ordering of the properties is the same as that given by looping over the property values of the object manually.

Examples

var obj = { foo: "bar", baz: 42 };console.log(Object.values(obj)); // ['bar', 42]// array like objectvar obj = { 0: 'a', 1: 'b', 2: 'c' };console.log(Object.values(obj)); // ['a', 'b', 'c']// array like object with random key orderingvar an_obj = { 100: 'a', 2: 'b', 7: 'c' };console.log(Object.values(an_obj)); // ['b', 'c', 'a']// getFoo is property which isn't enumerablevar my_obj = Object.create({}, { getFoo: { value: function() { return this.foo; } } });my_obj.foo = "bar";console.log(Object.values(my_obj)); // ['bar']// non-object argument will be coerced to an objectconsole.log(Object.values("foo")); // ['f', 'o', 'o']

Polyfill

To add compatible Object.values support in older environments that do not natively support it, you can find a Polyfill in the tc39/proposal-object-values-entries or in the es-shims/Object.valuesrepositories.
