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 @JaredFlomen/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function1(head): outputs the head (index[0]) of an array.
• function2(tail): outputs the tail (every value expect the head -> index[0]) of an array.
• function3(middle): returns the middle value of an array, that array will be 2 values if the length is even.
• funciton4(without): removes elements from an array, those elements must have the same type and value to what is being asked to be removed.
• funciton5(map): given an array containing strings, the map function will return a new array with the first letter in each string.
• funciton6(findKey): findKey will output a key from an object, using a callback function that determines which key to look for.
• funciton7(takeUntil): takeUntil will iterate through an array of strings until it stops, that break is determined through a callback function.
• funciton8(letterPositions): letterPositions outputs an object that contains each unique letter of a string, along with it's index position of that original string.
• function9(findKeyByValue): this function searches an object for a given value, and outputs it's corresponding key.
• funciton10(countLetters): this function returns an object containing each letter in a string, along with the amount of times that the letter is contained within the test string.
• function11(countOnly): countOnly outputs the amount of times a test string is found within an object, along with testing if that test string should be counted or not.
• function12(assertEqual): assertEqual is a blunt force tool designed to check if an input (actual) is the same type and value as an expected value.
• function13(assertObjectsEqual): assertObjectsEqual will test if two objects are the same, including: values, types and array lengths. Array lengths are tested if values are contained within a key instead of single numbers or strings.
• function14(eqObjects): eqObjects works with assertObjectsEqual by testing if two objects are the same.
• function15(eqArrays): eqArrays tests if two arrays are the same.
• function16(assertArraysEqual): assertArraysEqual is a function that outputs to the console if two arrays (an actual array and an expect array) are equal.
