OK Tools

This is my personal set of various JS tools I use in my projects. Zero dependencies.

Feel free to use them, but please keep in mind that I guarantee nothing.

Install

Via NPM: npm install ok-tools

For Angular, there is ok-angular-tools package wrapping these into handy pipes or directives.
