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

npm install @averenceanu/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function head: Retrieves the first element from the array.
• function tail: Retrieves every element except the head of the array.
• function middle: Takes in an array and return the middle-most element(s) of the given array.
• function assertArrayEqual: A message of success or failure printed to the console, letting us know if two arrays are a perfect match. To be implemented with eqArrays.
• function assertEqual: A message of success or failure printed to the console, letting us know if our functions are behaving as expected.
• function assertObjectsEqual: Takes in two objects and console.log an appropriate message to the console base on if they are a perfect match.
• function countLetters: Takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• function countOnly: When given an array and an object, it will return an object containing counts of everything that the input object listed.
• function eqArrays: Compares two arrays for a perfect match.
• function eqObjects: Takes in two objects and returns true or false, based on a perfect match.
• function findKey: Takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• function findKeyByValue: Takes in an object and a value. It returns the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• function letterPositions: Returns all the indices (zero-based positions) in the string where each character is found.
• function map: It takes in two arguments: an array to map, a callback function. It returns a new array based on the results of the callback function.
• function takeUntil: The function will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• function without: Returns a subset of a given array, removing unwanted elements.
