@vr-varad This PR cannot be accepted as is. The PR should only contain file changes for the package in question. This PR also includes all the commits from your take-map PR.

Based on the branch from which you are wanting to merge, you did not follow the contributing guide (see https://github.com/stdlib-js/stdlib/blob/develop/CONTRIBUTING.md#step-2-branch) and create a separate branch for your take-map commits. As a result your local develop branch has diverged from the main project develop branch.

Your main option at this point is to simply delete your local copy of stdlib, reclone, and start over, but this time creating a new branch before making your changes. For example,

$ git checkout -b feat/ssumkbn2

ohh.. sorry i didn't realise it
@kgryte I apologize for my negligence
I will reclone it and create a new pr u can delete this pr if required.
