augment-vir
This is a consolidated collection of small helper functions that I constantly use across all my JavaScript and TypeScript repos. I call these functions augments. These are things commonly placed within a "util", or "helpers", etc. directory; they don't really have anything in common with each other except that they have almost no dependencies.
For Node.js only augments, import augment-vir/dist/node-only. For Chai only imports, import augment-vir/dist/chai-only;
