[BioPhoton]

Documentation Related To Component:

The skipLast operator:
skipLast.ts

Please check those that apply

• typo
• documentation doesn't exist
• documentation needs clarification
• error(s)/adoption/updates in example
• needs example

Description Of The Issue

The detailed description is missing. Also, the see also links are missing.
We might want to improve this to serve a better more detailed description for the community.

Description

The detailed description can be improved. Here we should include that:

• it will always complete if the source completes
• it errors if source raises an error

See Also

We miss the see also section completely.

A suggested list for related operators could look like this:

 * @see {@link last}
 * @see {@link skip}
 * @see {@link skipWhile}
 * @see {@link skipUntil}

In case we also want to reference take operators (which is partially the case here) we also might want to include the following operators:

 * @see {@link first}
 * @see {@link take}
 * @see {@link takeWhile}
 * @see {@link takeUntil}
 * @see {@link takeLast}
