Lotide is a mini clone of the Lodash Library to practice crating a personal npm package. It's like lodash, but without all that extra stuff. Just the things you need to start your project.

// test for ../tail.js
const assert = require('chai').assert;
const tail = require('../tail');

  });

  it("Return the remaining array length of 2",()=>{
