A mini clone of the Lodash library.

Purpose

Install it:

npm install @zakiyaalfughi/lotide

Require it:

const _ = require('@zakiyaalfughi/lotide');

Documentation

The following functions are currently implemented:

• head(array): Function returns the first item in the array. The head function should not return the first element as an array. It should simply return the element itself.
• tail(array): Function returns the "tail" of an array, (i.e. everything except for the first item (head) of the provided array).
• eqArrays (array1, array2): Function takes in two arrays and returns true or false, based on a perfect match.
• assertArraysEqual(array1, array2): Function will take in two arrays and console.log an appropriate message to the console.
• middle(array): function takes in an array and return the middle-most element(s) of the given array.
• letterPositions(array): Function returns all the indices (zero-based positions) in the string where each character is found.
• countLetters(string): Function takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): Function takes an array and an object and returns a proper report on all the strings found in the input array, and their respective counts. Therefore it will need to return an object that can represent the stats. allItems: an array of strings that we need to look through itemsToCount: an object specifying what to count
• countOnly(allItems, itemsToCount):map function will take in two arguments:
• map(array, callback): Function returns a new array based on the results of the callback function.
• without(source, itemsToRemove): Function takes a primary array and a test array removes items from the primary array if they match the test array and then returns a new array with only the unique items from the primary array.
• takeUntil(array, callback): Function takes an array and a function returns everything in the array up until the function condition.
