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 @angusjk/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function1(assertArraysEqual): checks whether running two arrays through eqArrays gives the result we expect
• function2(assertEqual): checks whether two given strings, numbers, or booleans are the same or not
• function3(assertObjectsEqual): checks whether running two objects through eqObjects gives the result we expect
• function4(countLetters): returns the number of instances of each letter within a given string
• function5(countOnly): takes an array of names and a list of names to count instances of in that array
• function6(eqArrays): tells whether two given arrays are equal or not
• function7(eqObjects): tells whether two given ojbects are equal or not
• function8(findKey): returns a value of a given object when passed a key corresponding to that value
• function9(findKeyByValue): returns a key of a given object when passed a value corresponding to that key
• function10(flatten): takes in a nested array and returns a single arrays containing all values
• function11(head): returns the first value in a given array
• function12(letterPosition): returns the indexes of each letter contained in a given string
• function13(luhn_algorithm): checks whether a given number is valid by the standards of a luhn algorithm
• function14(map): returns an array containing the letter found at a given index of each string in an array
• function15(maxProfit): returns the largest difference between any number and any subsequent number in a given array
• function16(middle): returns the value(s) found at the middle of a given array
• function17(poppin_bottles): algorithm for determining how many bottles can be purchased and returned with a given amount of money
• function18(tail): returns all but the first value in a given array
• function19(takeUntil): returns all values in an array that match a given criteria
• function20(without): returns an array containing only values not matching the given criteria for removal
