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 @braverdan/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function1(assertArraysEqual): Checks two arrays to ensure each item is equivilant. Even if the items are arrays themselves.
• function2(assertEqual): Gives out a true of false value for two inputs (expected and actual) to make sure they are equal. Does not work for objects.
• function3(assertObjectsEqual): Compares two objects and all their keys regardless of type to ensure they are equal. Also works on arrays.
• function4(countLetters): Counts the characters of a string and provides an object with the count of every character.
• function5(countOnly): Counts a given selection of items out of an array, outputs an object with each item and the count of said item.
• function6(eqArrays): Takes two arrays and ensures that they are equal, indluing nested arrays. assertArraysEqual is based on this function.
• function7(eqObjects): Takes two objects and check that they and their keys are equal. assertObjectsEqual is based on this function.
• function8(findKey): Find an object's first matching key based on the value.
• function9(findKeyByValue): Find an object's key given a value.
• function10(flatten): Takes a single layer nested array and flattens all items into a non nested array.
• function11(head): Outputs the first item of an array.
• function12(letterPositions): Given a string, produces an object with the index positions of each character.
• function13(map): Takes an array and allows for a callback function to act on each of the items.
• function14(middle): Finds the middle item or middle two items of a given array.
• function15(tail): Produces an array without the first element of the given array.
• function16(takeUntil): Produces an array of items up until a given input out of a given array.
• function17(without): Given an array to manipulate and a list of items to remove from said array, produces an array without the items given to remove.
