Individually-Wrapped Utilities
Fast and small implementations of common things.
Individually wrapped so you can include only the functions you need for your project. No code bloat!
All Typescript-ready (and written).
Usage
Use through npm, or get the source from Github.
Functions
From the npm package, Look in /dist/src/*.d.ts for documentation on the individually-wrapped functions. (Even if you don't use Typescript, these files are best for documentation, because they are just the function declaration, with types and documentation, without the implementations getting in the way.)
From the source on Github, look in /src/*.ts for the same, and look ing /test/*.test.ts for unit tests that reinforce how the tools work.
