Hey @kgryte ,
If this issue is still to be worked on, I would like to work, please assign.

@Pushpendra766 Yes, this package is still needed. I just assigned you. It would be good to model the implementation closely after @stdlib/string/first, as the package should support the same modes and have a similar API.

[Pushpendra766]

Sure, will work on it then.

[kgryte]

@Pushpendra766 To clarify, please first work on @stdlib/string/base/last, and model after the following package: https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/string/base/first

[kgryte]

This feature request is actually comprised of multiple new packages, and I advise working on one at a time. The easiest and most straightforward is @stdlib/string/base/last. From there, we can move to the others after you've gotten the first successfully merged.

[Pushpendra766]

Sure, thanks for providing a reference.
