JavaScript utilities covering a wide breadth of functionality

Breadth.JS

Where to find JavaScript utilities you might need. Often times I have found myself having to search stackoverflow for an obscure utility, or just default to writing my own because finding one on NPM that works properly would be energy consuming. So this list hopes to list out as many utilities as possible and where you can find them, to speed up coding your project!

As an additional note, these are basically the libraries you should learn to give you an edge in terms of speed when getting things done. They are typically long-standing and "stable" APIs, and learning them will be a skill you could transfer to any JavaScript or Node.js project.
