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('@ahana15/lotide');
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
head(...): returns the first item in the array
middle(...): take in an array and return the middle-most element(s) of the given array
tail(...): returns everything except for the first item (head) of the provided array
countOnly(...): given an array and an object, it will return an object containing counts of everything that the input object listed.
countLetters(...): return an object where each unique character encountered is a property of the object and the value for that property/key should be the number of occurrences for that character.
findKey(...): takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
findKeyByValue(...):which takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
flatten(...): take in an array of arrays and return a "flattened" version of the array.
letterPositions(...): takes in a string and returns an object with unique letters and the index position of the letter occurences.
map(...): map function will take in two arguments:An array to map and a callback function. The map function will return a new array based on the results of the callback function.
takeUntil(...): this will keep collecting items from a provided array until the callback provided returns a truthy value.
without(...): return a subset of a given array, removing unwanted elements
