Function modeOrDefault

modeOrDefault<TElement, TKey>(
source: Iterable<TElement>,
keySelector?: Selector<TElement, TKey>,
): TElement | null
Returns the element that appears most frequently in source, or null when the iterable is empty.
Type Parameters
- TElement
  Type of elements within the source iterable.
- TKey
  Type of key produced by keySelector.
Parameters
- source: Iterable<TElement>
  The source iterable to inspect.
- OptionalkeySelector: Selector<TElement, TKey>
  Optional selector that projects each element to the key used for frequency counting. Defaults to the element itself.
Returns TElement | null
The first most frequent element, or null when source contains no elements.
Throws
Re-throws any error thrown while iterating source or executing keySelector.

Remarks
Unlike mode, this function communicates the absence of elements by returning null. When multiple keys share the maximum frequency, the element encountered first is returned.
Example
```
const winner = modeOrDefault<number>([]);
console.log(winner); // null
```
