Function extreme

extreme<T>(
f: (a: T, b: T) => number,
): (values: Iterable<T>) => { max: T; min: T } | undefined
Finds both the minimum and maximum values in an iterable based on a comparison function.
Type Parameters
- T
  Type of elements in the iterable
Parameters
- f: (a: T, b: T) => number
  Comparison function that returns a number (negative if a < b, 0 if a = b, positive if a > b)
Returns (values: Iterable<T>) => { max: T; min: T } | undefined
A function that takes an iterable and returns an object with min and max properties, or undefined if the iterable is empty
Example
```
// Find min and max numbers
const result = extreme((a, b) => a - b)([3, 1, 4, 1, 5, 9, 2, 6])
// Result: { min: 1, max: 9 }
```
Example
```
// Find min and max string lengths
const result = extreme((a, b) => a.length - b.length)(["apple", "banana", "kiwi", "strawberry"])
// Result: { min: "kiwi", max: "strawberry" }
```
Example
```
// With an empty iterable
const result = extreme((a, b) => a - b)([])
// Result: undefined
```
