Function elementAtOrDefault

elementAtOrDefault<TElement>(
source: Iterable<TElement>,
index: number,
): TElement | null
Retrieves the element at the specified zero-based index or returns null when the index is out of range.
Type Parameters
- TElement
  Type of elements within the source iterable.
Parameters
- source: Iterable<TElement>
  The source iterable.
- index: number
  Zero-based position of the element to retrieve.
Returns TElement | null
The element at index, or null when source is shorter than index + 1 or when index is negative.
Remarks
Use this overload when out-of-range access should produce a sentinel value instead of throwing an exception.
Example
```
const numbers = [1, 2, 3, 4, 5];
const element = elementAtOrDefault(numbers, 2);
console.log(element); // 3

const element2 = elementAtOrDefault(numbers, 10);
console.log(element2); // null
```
