ElementAtOrDefault

Description:

This method is similar to ElementAt . However it returns null in case of either source is empty or index is out of range, instead of an exception.

Sample:

let empty = [];
let items = ['One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten'];

let elementAtOrDefault = items.asEnumerable().elementAtOrDefault(5);
console.log(elementAtOrDefault);

elementAtOrDefault = empty.asEnumerable().elementAtOrDefault(5);
console.log(elementAtOrDefault);
