Function multimode

multimode<TElement, TKey>(
source: Iterable<TElement>,
keySelector?: Selector<TElement, TKey>,
): IEnumerable<TElement>
Produces the elements whose occurrence count is tied for the highest frequency in source.
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 IEnumerable<TElement>
A deferred sequence containing one representative element for each frequency mode.
Throws
Re-throws any error thrown while iterating source or executing keySelector.

Remarks
Enumeration of the result buffers the entire source to compute frequency counts before yielding results. When multiple elements share a key, only the first occurrence is emitted.
Example
```
const modes = multimode([1, 2, 2, 3, 3]).toArray();
console.log(modes); // [2, 3]
```
