U-FO (useless-info)

Useful JavaScript library to manage easily types and classes in your application

What is it

This library offer:

• Some informative functions about your values
• A bundle of useful functions to check conditions and handle consistency.

How it works

After you have imported the package:

import * as UFO from "useless-info";

You can call the functions you need, for example:

let myArray = [objClassA,objClassB,objClassA,objClassA];
UFO.isArrayClassConsistent(myArray);
// Expected result : false

let myArray = [34,{},'hello',4.6];
UFO.getElementsFromArrayWithType(myArray,'float');
// Expected result : [4.6]

You can also import only some functions, for example:

import { isArray, isFloat } from "useless-info";
