@audrey-audrey/lotide v1.0.0

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 @audrey-audrey/lotide

Require it:

const _ = require('@audrey-audrey/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): takes in two objects and returns a message to specify if the two objects are equal
• assertEqual(actual, expected): takes in two primitive datas and returns a message to specify if the datas are equal

• assertObjectsEqual(actual, expected): takes in two objects and returns a message to specify if the two objects are equal

• countLetters(sentence): takes in a sentence (as a string) and returns a count of each of the letters in that sentence

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

• eqArrays(array1, array2): takes in two objects and returns a true if the two objects are equal

• eqObjects(object1, object2): takes in two objects and returns true if the two objects are equal

• findKey(object, callback): 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.

• findKeyByValue(object, value): takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• head(array): takes an array and returns the first element of the array
• letterPositions(sentence): takes in a string and returns all the indices (zero-based positions) in the string where each character is found
• map(array, callback): takes an array and a callback and returns a new array based on the results of the callback function
• middle(array): takes an array and returns the middle element of the array
• tail(array): takes an array and returns all the elements of the array without the first element
• takeUntil(array, callback): takes an array and a callback and returns "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• without(array, itemsToRemove): takes in an array and an itemsToRemove array and returns an array without any elements found in itemsToRemove
