/*
--------------- 8 Kyu - Lost Without a Map ------------------

Instructions:

Given an array of integers, return a new array with each value doubled.

For example:

[1, 2, 3] --> [2, 4, 6]

-------------
Sample Tests

const chai = require("chai");
const assert = chai.assert;
chai.config.truncateThreshold=0;

describe("Basic tests", ()=>{
  it("Fixed tests", () => {
    assert.deepEqual(maps([1, 2, 3]), [2, 4, 6]);
    assert.deepEqual(maps([4, 1, 1, 1, 4]), [8, 2, 2, 2, 8]); 
    assert.deepEqual(maps([2, 2, 2, 2, 2, 2]), [4, 4, 4, 4, 4, 4]); 
  });
});

Psuedo Code:
-.map(x => x * 2)
