Additional solution for 085

[optimizasean]

interface Scores extends Record<string, number> {
  math: number;
  english: number;
  science: number;
}

// @ts-expect-error science is missing!
const scores: Scores = {
  math: 95,
  english: 90,
};

scores.athletics = 100;
scores.french = 75;
scores.spanish = 70;

I extended Record (but then realized it was a type alias, not an interface...and it worked!). Thought it was interesting to discover and might be worth adding in to 085 as another alternate solution since this seems to be a modern TypeScript pattern people take advantage of.

Not sure if this comes up later in a different module (only halfway through so far)!

I also noticed it is only required to define science: number; not also math and english in the interface/type as required to pass the check.
Got confused for a bit since interfaces and types both require all non optional ? values to be defined on instantiation and I thought maybe interfaces were special and had to check the docs.

So I read the docs and ended up trying to learn how the exercise worked -> on @ts-expect-error <MESSAGE> throws an error if there is no error...so any single key added not defined by the const (science, welsh, art, ...) on the following line would trigger an error (because that key is not being instantiated even though it is required) which is silenced by the expect comment.
If it is defined there is no error and then it shows the message after the expect.

Genius way to prompt the user to complete the exercise and add the "mandatory" subjects!
Also a great look for me into error annotations, interfaces, and mandatory/optional parameters!

Loving the course so far!
