JavaScript Object getOwnPropertyDescriptor() Method
Last Updated :
12 Jul, 2025
The Object.getOwnPropertyDescriptor() method in JavaScript is a standard built-in object that enables the full information on a property to be accessed and returns a property descriptor for the own property of a given object.
Syntax:
Object.getOwnPropertyDescriptor( obj, prop )
Parameters: This method accepts two parameters as mentioned above and described below:
- obj: This parameter holds the object in which the property is to be looked.
- prop: This parameter holds the name or Symbol of the property whose description is to be retrieved.
Return value: This method returns a property descriptor of the given property or undefined depending upon the existence of the object.
Below examples illustrate the Object.getOwnPropertyDescriptor() method in JavaScript:
Example 1: In this example, we will check if an object contains some property or not using the Object.getOwnPropertyDescriptor() method in JavaScript.
javascript
const geeks1 = {
prop1: "GeeksforGeeks"
}
const geeks2 = {
prop2: "Best Platform"
}
const geeks3 = {
prop3: "And Computer science portal"
}
const descriptor1 = Object.getOwnPropertyDescriptor(geeks1, 'prop1');
const descriptor2 = Object.getOwnPropertyDescriptor(geeks2, 'prop2');
const descriptor3 = Object.getOwnPropertyDescriptor(geeks3, 'prop3');
console.log(descriptor1.enumerable);
console.log(descriptor2.enumerable);
console.log(descriptor1.value);
console.log(descriptor2.value);
console.log(descriptor3.enumerable);
console.log(descriptor3.value);
Output:
true
true
"GeeksforGeeks"
"Best Platform"
true
"And Computer science portal"
Example 2: In this example, we will check if an object contains some property or not using the Object.getOwnPropertyDescriptor() method in JavaScript.
javascript
let geek, result;
geek = { get foo() { return 17; } };
d = Object.getOwnPropertyDescriptor(geek, 'foo');
console.log(d)
geek = { bar: 42 };
d = Object.getOwnPropertyDescriptor(geek, 'bar');
console.log(d)
geek = { [Symbol.for('baz')]: 73 }
d = Object.getOwnPropertyDescriptor(geek, Symbol.for('baz'));
console.log(d)
geek = {};
Object.defineProperty(geek, 'qux', {
value: 8675309,
writable: false,
enumerable: false
});
d = Object.getOwnPropertyDescriptor(geek, 'qux');
console.log(d)
Output:
Object { get: get foo() { return 17; }, set: undefined, enumerable: true, configurable: true }
Object { value: 42, writable: true, enumerable: true, configurable: true }
Object { value: 73, writable: true, enumerable: true, configurable: true }
Object { value: 8675309, writable: false, enumerable: false, configurable: false }
