is-useless

why npm why

Why?

Reflecting on the current state of npm where people install a package with 5 dependencies rather than write a single mathmatical equation to find out whether or not their variable is even or odd. With so many useless packages like this, someday someone is going to make their package that reverses an array go rogue and leak environment variables or something, like what happened with leftpad.

installation

Using npm:

npm i is-useless

In Node.js:

const isuseless = require("is-useless").isuseless;

Usage

const isuseless = require("is-useless").isuseless;

console.log(isuseless(process.env.CREDIT_CARD_NUMBER)); // may or may not send to servers for product improvement

You can also enable some useful logs with the second paremeter

const isuseless = require("is-useless").isuseless;

console.log(isuseless(process.env.CREDIT_CARD_NUMBER, true)); // outputs some extremely useful logs

If you want it to run slower, use the third paremeter!

const isuseless = require("is-useless").isuseless;

console.log(isuseless(process.env.CREDIT_CARD_NUMBER, false, true)); // runs kind of slower
