A mini clone of the Lodash library.
BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.
This project was created and published by me as part of my learnings at Lighthouse Labs.

const _ = require('@username/lotide');
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertArraysEqual(...): given two arrays, prints out a string indicating if they are equal
assertEqual(...): compares two values and prints out a string indicating if they are equal
assertObjectsEqual(...): given two objects, prints out a string indicating if they are equal
countLetters(...): given a string, returns an object containing a count of each letter in the string
countOnly(...): given an array and an object of keys and booleans as values, returns a count of those objects in the array with a value of true in the given object
eqArrays(...): given two arrays, returns a boolean indicating if they are equal
eqObjects(...): given two objects, returns a boolean indicating if they are equal
findKey(...): given an object and a callback, returns the key where the callback evaluates to true
findKeyByValue(...): given an object and a value, returns the key in the object based on the value
flatten(...): takes a nested array and returns a new array without nested arrays
head(...): takes an array and returns the first element of the array
lettersPositions(...): takes a string and returns an object containing an array for each letter containing their index in the string
map(...): takes an array and a callback function and returns a new array based on the given callback
middle(...): takes an array and returns a new array containing the middle element, if the array contains an odd number of items. Otherwise it returns a new array containing the middle two elements (if the array contains an even number of item)
