Package dont have any dependency, old functions (FileSystem, Music, ...etc) wil be returned soon

Not great, not perfect, but better than nothing.

I removed some functions (FileSystem, Music, ...etc) for more compatibility with environments. I will return it soon.

Usage

const JsUseful = require('jsuseful')

console.log(JsUseful.Random.number(2, 6))
// -> 5

or

const { Random, Values } = require('jsuseful')

console.log(Random.number())
// -> 87
