const to hold changing value?

Why use a const when the value is expected to change? I thought that was the purpose of let?

It's works fine in the example, which is confusing...

const in JavaScript isn't really a "true" constant. If you have an object that's declared as a constant, you can just mutate the key-value pairs. But yes you should be using let if you expect the value to change.
