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 @nyamashiro722/lotide

Require it:

const _ = require('@nyamashiro722/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• function head(array): returns the first item in an array

• function tail(array): returns an array with every element except the first element

• function middle(array): returns the middle item of an array. If the array is an even number, returns an array of the middle two items

• function assertArraysEqual(actual, expected): assert whether two arrays are equal

• function assertEqual(actual, expected): assert whether two non-object values are equal

• function assertObjectsEqual(actual, expected): assert whether two objects are equal

• function countLetters(input): counts how many letters there are in a string input

• function countOnly(allItems, itemsToCount): takes in a collection of items and return counts for a specific subset of those items

• function eqArrays(firstArray, secondArray): returns whether the two input arrays are equal or not

• function eqObjects(firstObject, secondObject): returns whether the two input objects are equal or not

• function findKey(object, callback): takes an object and callback and returns the first key for which the callback returns a truthy value

• function findKeyByValue(object, value): searches for a key on an object where its value matches a given value

• function flatten(array): takes an array and "flattens" the array. Can handle an unlimited amount of nested arrays

• function letterPositions(sentence): returns all the indices (zero-based positions) in the string where each character is found

• function map(array, callback): returns a new array where items are a result of calling the callback function on each item of the array

• function takeUntil(array, callback): keeps collecting items from a provided array until the callback provided returns a truthy value.

• function without(source, itemsToRemove): returns a subset of a given array, removing unwanted elements
