JavaScript Object.getOwnPropertySymbols()

getOwnPropertySymbols() Syntax

The syntax of the getOwnPropertySymbols() method is:

Object.getOwnPropertySymbols(obj)

Here, getOwnPropertySymbols() is a static method. Hence, we need to access the method using the class name, Object.

getOwnPropertySymbols() Parameters

The getOwnPropertySymbols() method takes in:

• obj - the object whose symbol properties are to be returned.

getOwnPropertySymbols() Return Value

The getOwnPropertySymbols() method returns an array of all symbol properties found in the given object.

Note: Object.getOwnPropertySymbols() returns all symbol properties of the object while Object.getOwnPropertyNames() returns the string properties.

Example: JavaScript Object.getOwnPropertySymbols()

In the above program, we have created an object superhero1 with the following properties:

• symbols - id and name
• string - age

Then, we used the getOwnPropertySymbols() method on superhero1 to list its symbol properties.

As expected, we get an array listing only the symbols id and name as the output.
