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 @rofrado9178/lotide

Require it: const _ = require("@rofrado9178/lotide");

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arrayResult,expectedArrayResult): function that will test a comparison between two arrays and give return true or false

• assertEqual(result , expected): function that will test two values the result and expected value and will return boolean

• assertObjectsEqual(result, expected): function that will test if two object is identical or not, with the same key object and values

• countLetters("string"): function that will turn given string into key object for every of each letter and count it

• countOnly(array, object): function that will return an object containing counts of everything that the input object listed

• eqArray(array1 , array2): function that will compare two of array and return true or false base on perfect match

• eqObject(object1 , object2): function that will compare if two object is identical or not base on key and value

• findKey(object, callback): function that takes in object and callback as a parameter,it will scan and return the first key that callback return true

• findKeyByValue(object, value): function that takes two parameters object and value, and will return the key if match value found

• head(array): function that will run through an array and will return only the head of an array (first element in the array)

• letterPositions(words): function that will return an object of each letters as a key and an index position as a value for each letters

• mapFunction(array, callback): function will return a new array based on the results of the callback function

• middle(array): function that takes an array as a parameter and will return an array with out the first and the last element from given array

• tail(array): function that takes an array an array as a parameter and will return an array with only the last index of given array

• takeUntil(array , callback): function that takes two parameters an array and callback, the function will return a slice of the array with elements taken from the begining, it should keep going until the callback / predicate returns a truthy value.

• without(array, itemToRemove): function that should takes in an array and itemToRemove array, it should return a new array with only those element from source that are not present in the itemsToRemove array.
