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 @sasu.osayande/lotide

Require it:

const _ = require('@sasu.osayande/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• const assertArraysEqual = function(array1, array2) : used in conjunction with eqArrays to evaluate two arrays.

• const assertEqual = function(actual, expected) : implemented our own assert function.

• const assertObjectsEqual = function(actual, expected) : assertion to help us test functions that return objects.

• const countLetters = function (sentence) : used to return a count of letters in a given string.

• const countOnly = function(allItems, itemsToCount) : used to return an object containing counts of the input object from an array.

• const eqArrays = function(array1, array2) : used to compare two arrays.

• const eqObjects = function(object1, object2) : used to compare two objects.

• const findKey = function(object, callback) : used to return the first key for which a callback function returns a truthy value.

• const findKeyByValue = function(object, value) : used to return a key by inputing the value of that key.

• const head = function(first) : retrieves the first element in an array.

• const letterPositions = function(sentence) : used to return an array of indices of a character in a string.

• const map = function(mapArray, callbackFn) : implemented our own version of map().

• const middle = function(array) : retrieves the middle-most elements of a given array.

• const tail = function(minusHead) : returns a new array without the first element ("head") of the original array.

• const takeUntil = function(array, callback) : returns a slice of an array, stopping/excluding the element equal to the callback fn.

• const without = function(source, itemsToRemove) : removes elements from the first array that are found in the second array.
