How can I make changes to an array that is stored within an object, according to the freeCodeCamp JavaScript challenge?

As a JavaScript developer, I'm frequently asked whether it's feasible to access an object's property using a dynamic name. To achieve this, we can make use of bracket notation while referencing the object property. Here's an example: 
const something = { bar: "Foobar!" };
const foo = 'bar';
something[foo]; // This will retrieve the value of something.bar, returning "Foobar!"
I hope this clears up any confusion you may have had. Let me know if you need any further assistance.

Yes, it's possible to access a property of an object using a dynamic name in JavaScript. Instead of using dot notation (something.foo), you can use square bracket notation (something[foo]) to achieve this. Here's an updated version of the code you provided that should work: 
const something = { bar: "Foobar!" };
const foo = 'bar';
console.log(something[foo]); // Output: Foobar!
By using square bracket notation and passing in the dynamic variable foo, we can access the bar property of the something object and log its value to the console.
