Let's add a key with the Symbol
type for some object. Let for example
we have the following object:
let obj = {a: 1, b: 2, c: 3};
Let's add a new element to this object with a key from a symbol:
let sym = Symbol();
obj[sym] = 'text';
Make an object that has a symbol as one of its keys.
Output the object you created to the console.
