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 @shamayal/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(firstArray, secondArray): an assert function that compares two arrays and logs a message to the console to tell us if they are a match or not
• assertEqual(firstArray, secondArray): an assert function that compares two values and logs a message to the console to tell us if they are a match or not
• assertObjectsEqual(object1, object2): an assert function that compares two objects and logs a message to the console to tell us if they are a match or not
• countLetters(sentence): returns an objects with the count of each of the letters in a sentence
• countOnly(allItems, itemsToCount): returns an object containing counts of everything from an array that the input object listed
• eqArrays(firstArray, secondArray): takes in two arrays and returns true or false, based on a perfect match
• eqObjects(object1, object2): takes in two objects and returns true or false, based on a perfect match
• findKey(objectToScan, callback): returns the first key in an object for which the callback returns a truthy value
• findKeyByValue(objectToSearch, valueToFind): takes in an object and a value and returns the first key which contains the given value
• head(arrayElements): retrieves the first element of an array
• letterPositions(sentence): returns an object with all the indices of the letters in a string
• map(array, callback): returns a new array based on the result of the callback function
• middle(arrayElements): returns an array with only the middle element(s) from the provided array
• tail(arrayElements): retrieves every element except the first element of an array
• takeUntil(array, callback): returns a slice of the array with elements taken from the beginning until the callback returns a truthy value
• without(sourceArray, itemsToRemove): removes specified items from an array and returns a new array without those items
• flatten(array): given an array with other arrays inside, it can flatten it into a single-level array
