/Global_Objects/Object/getOwnPropertyNames) ,
you can get all symbol properties of a given object as an array of symbols.
Note that [ ` Object.getOwnPropertyNames() ` ](/en-
US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertyNames)
itself does not contain the symbol properties of an object and only the string
properties.

As all objects have no own symbol properties initially, `
Object.getOwnPropertySymbols() ` returns an empty array unless you have set
symbol properties on your object.

##  Examples

###  Using Object.getOwnPropertySymbols()

js

    
    
    const obj = {};
    const a = Symbol("a");
    const b = Symbol.for("b");
    
    obj[a] = "localSymbol";
    obj[b] = "globalSymbol";
    
    const objectSymbols = Object.getOwnPropertySymbols(obj);
    
    console.log(objectSymbols.length); // 2
    console.log(objectSymbols); // [Symbol(a), Symbol(b)]
    console.log(objectSymbols[0]); // Symbol(a)
