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 @timjquigg/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Compares 2 arrays and confirms if they are deeply equal
• assertEqual(actual, expected): Compares 2 primitive values and confirms if they are equal
• assertObjectsEqual(actual, expected): Compares 2 objects and confirms if they are deeply equal
• countLetters(str): Accepts a string input and produces an object with the total occurances of each letter in the string
• countOnly(allItems, itemsToCount): Accepts an array of values and produces an object with the total occurances of items that appear in itemsToCount
• eqArrays(arrOne, arrTwo): Accepts two arrays and does a deep equals comparison
• eqObjects(object1, object2): Accepts two objects and does a deep equals comparison
• findKey(obj, callback): Returns the key of an object who's value meets the criteria provided in the callback function
• findKeyByValue(obj, targetValue): Returns the key of an object who's value is the target value
• flatten(arr): Accepts a nested array and returns of flattened array
• head(input): Accepts and array and returns the first element of the array
• letterPositions(sentence): Accepts a string and returns an object with each letter in the string as keys and values being arrays of the index of each occurance of the letter
• map(arr, callback): is an implimentation of the built-in Array.Prototype.map() function
• middle(arr): Accepts an array as input and returns the middle element(s)
• tail(input): Accepts an array as input and returns a new array with the first element removed
• takeUntil(array, callback): Accepts an array as input and returns a new array containing all of the elements up until the conditions of the callback function are met
• without(source, itemsToRemove): Accepts an array as input and returns a new copy with the items in itemsToRemove removed
