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 @username/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function head (...): returns the first item in the array
• function tail(...): returns the "tail" of an array: everything except for the first item (head) of the provided array
• function middle(...): returns an array one with either one middle element or two middle elements for a given array with odd or even number of elements accordingly
• function assertArraysEqual (...): takes in two arrays and logs an appropriate message to the console
• function assertEqual(...): compares the two values it takes in and print out a message telling us if they match or not
• function assertObjectsEqual(...): takes in two objects and console.log an appropriate message to the console
• function countLetters (...): takes in a string and returns a count of each of the letters in the string
• function countOnly(...): takes in a collection of items and returns counts for a specific subset of those items
• function eqArrays(...): takes in two arrays and returns true or false, based on a perfect match
• function eqObjects (...): take in two objects and returns true or false, based on a perfect match (checks primitive return types only)
• function findKey(...): takes in an object and a callback, scans the object and returns the first key for which the callback returns a truthy value
• function findKeyByValue(...): searches for a key on an object where its value matches a given value
• function letterPositions (...): returns all the indices in the string where each character is found
• function map(...): takes an array and a callback function and returns a new array based on the results of the callback function
• function takeUntil(...): collects items from a provided array until the callback provided returns a truthy value
• function without(...): returns a subset of a given array, removing unwanted elements
