trimTrailingEmptyElements() function

Returns an array with trailing empty elements removed. For example, [1, 2, 3, null, undefined, ''] becomes [1, 2, 3]. This is useful for FHIR arrays, which by default must maintain the same length, but while editing we may want to trim trailing empty elements.

Signature:

export declare function trimTrailingEmptyElements<T>(arr: T[] | undefined): T[] | undefined;

Parameters

Parameter	Type	Description
arr	T[] | undefined	The input array.

Returns:

T[] | undefined

The array with trailing empty elements removed.
