@dinaganai/lotide v1.0.1

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 @dganai/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns first element of an array
• tail(arr): returns tail of an array (not including first element)
• middle(array): returns middle most elements of given array
• assertEqual(actual, expected): prints "✅✅✅ Assertion Passed" or "🛑🛑🛑 Assertion Failed" when comparing two values to see if they match or not
• assertArraysEqual(array1, array2): prints "✅✅✅ Assertion Passed" or "🛑🛑🛑 Assertion Failed" when comparing to see if two arrays are equal
• eqArrays(array1, array2): takes in two arrays and returns true or false, based on a perfect match
• without(source, itemsToRemove): returns a subset of the given array, removing unwanted elements
• countOnly(allItems, itemsToCount): takes in a collection of items and returns counts for a specific subset of those items
• countLetters(string): takes in a sentence as a string then returns a count of each of the letters in that sentence
• letterPositions(sentence): returns all the indices in the string where each character is found
• findKeyByValue(object, value): scans the object and returns the first key that contains a given value; undefined if no value
• eqObjects(object1, object2): returns true or false based on if two object are a match perfect match or not
• assertObjectsEqual(actual, expected): prints "✅✅✅ Assertion Passed" or "🛑🛑🛑 Assertion Failed" when comparing two objects to see if they match or not
• map(array, callback): returns new array based on results of the callback function
• takeUntil(array, callback): returns slice of the array with elements taken from the beginning, until the callback returns a truthy value
• findKey(object, callback): scans object and returns the first key for which the callback returns a truthy value; if no key, returns undefined
