Create and Publish Your First NPM Package

I created my first package in the year 2020.

For all the packages I initially created so far, one of them seems to at least reaches a lot of developers and invited some friendly contributors to enhance the existing codes. It is such a privilege that I become part of that package and helping those developers who are using our open source package.

This package is: check-password-strength
