Array.prototype.sort() with a compare function throwing errors

I have a list of objects that I need to sort, for example
```javascript
const scores = [
{ name: "Alice", score: 85 },
{ name: "Bob", score: 92 },
{ name: "Charlie", score: 78 },
{ name: "David", score: 95 },
];

// Sort the scores array by the "score" property in ascending order
scores.sort((a, b) => a.score - b.score);
```

However, AppSync errors out when I try to save my code
```
@aws-appsync/no-function-passing: Functions can not be passed as an argument
```

This is problematic and doesn't make a ton of sense because 1) passing functions as arguments to other stuff like `Array.prototype.reduce` works fine, and 2) VTL had a sort function that could sort objects in a list by an attribute. I'm trying to rewrite all my functions in Javascript but there are some that I've had to continue using VTL for and others where I've had to find ugly creative workarounds to get sorting to work.

Start with the JavaScript example and the reported @aws-appsync/no-function-passing error, then determine whether comparator functions are supported by the AppSync JavaScript runtime. Done means Array.prototype.sort accepts a comparator for object arrays without that error, with behavior documented or demonstrated for the example.
