@jacquelinejg/lotide v1.0.0

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 @jacquelinejg/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function assertArraysEqual (paramOne, paramTwo): Utilizes the eqArray function to compare two arrays and assert that they are or are not equal.
• assertEqual = function(actual, expected): prints to the console when an expected outcome is not met (fails) so that we can look into why. Works on primitive data.
• assertObjectsEqual = function(actual, expected): Evaluates objects with the help of eqObjects funtion to console.log a message to assert if the objects pass or fail the expected test.
• countLetters = function(string): Takes in a string and returns a tally count of each of the letters in that sentence.
• countOnly = function(allItems, itemsToCount): Takes in a collection of items and returns the counts for a specific subset of those items.
• function eqArrays(arrOne, arrTwo): Compares the contents of two arrays to find the perfect match.
• eqObjects = function(object1, object2): Takes in two objects and returns true or false, based on a whether the objects match.
• findKey = (obj, check): 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.
• function findKeyByValue(object, value): Searches for a key in an object where the value matches a given value.
• head = function(arr): Returns the first element from the array.
• letterPositions = function(sentence): Returns all of the index positions in the string where each character is found.
• map = function(array, callback): Returns a new array based on the results of the callback function implimented.
• middle = function(arr): Returns the middle number of an array with an odd length, and the middle two numbers of an array with an even length.
• tail = function(arr): Returns the tail of an array.
• takeUntil = function(array, callback): Collects items from a provided array until the callback provided returns a truthy value.
• without (source, itemsToRemove): Returns a subset of a given array after removing the unwanted elements.
