Lotide

A mini clone of the Lodash library.

Purpose

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.

Usage

Install it:

npm install @granttaylor448/lotide

Require it:

const _ = require('@granttaylor448/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• const assertArrayEqual = function(actual, expected): Is passed two arrays and determines if they are equal or not.
• const assertEqual = function(actual, expected): Is passed two strings or numbers and determines if they are equal or not.
• const assertObjectsEqual = function(actual, expected): Is passed two objects and determines if they are equal or not.
• const countLetters = function (string): Takes in a string and counts the number of letters in it.
• const countOnly = function(allItems, itemsToCount): Takes in an array of strings and only returns what the object itemsToCount specifies.
• const eqArrays = function (actual, expected): Takes two arrays and outputs whether or not they are equal to each other.
• const eqObjects = function(object1, object2): Takes two objects and outputs if they are equal or not.
• const findKey = function(object, callback): Takes an object and a key: value and returns its key.
• const findKeyByValue = function (object, value): Takes an object and a value and returns the key for that value.
• const flatten = function(array): Given an array with embedded arrays inside of it it will return a single array.
• const head = function(actual): Returns the first item in an array.
• const letterPositions = function(sentence): Takes in a string and returns an object that tells when each letter in the string occurs.
• const map = function(array, callback): Takes in an array of strings or numbers and returns a value for each item in the array of that index.
• const middle = function(array): Takes in an array and returns the middle value. If the array length is even it will return the two middle values.
• const tail = function(actual): Takes in an array and returns the last value in the array.
• const takeUntil = function(array, callback): Takes in an array and returns a new array that stops where the callback indicates.
• const without = function(array, remove): Takes in an array and an item to remove from the array and returns a new array without that item.
