What will be the output of the following JavaScript code?
const object1 = {};
a = Symbol(‘a’);
b = Symbol.for(‘b’);
object1[a] = ‘harry’;
object1[b] = ‘derry’;
const objectSymbols = Object.getOwnPropertySymbols(object1);
console.log(objectSymbols.length);
a) 0
b) 2
c) 1
d) error

Answer: b
Explanation: The Object.getOwnPropertySymbols() method returns an array of all symbol properties found directly on an object. This method returns an empty array unless you have set symbol properties on your object.
