@aarijanwer/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 @aarijanwer/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns array[0] as the head
• tail(array): returns all itmes after the head of array as an array
• middle(array): returns the middle of array (one item if odd, two items if even, none if array.length <=2)
• assertArraysEqual(actual, expected): assert function checking if arrays actual === expected, doesn't return only prints to console.log
• assertEqual(actual, expected): assert function checking if primitive data types actual === expected, doesn't return only prints to console.log
• assertObjectsEqual(actual, expected): assert function checking if objects actual === expected, doesn't return only prints to console.log
• countLetters(phrase): return an object that enumerates each letter of the string phrase
• countOnly(allItems, itemsToCount): given an array allItems and an object itemsToCount, it will return an object containing counts of everything that the input object listed.
• eqArrays(array1, array2): returns true if array1 and array2 have the exact same contents and same length
• eqObjects(object1, object2): returns true if object1 and object2 have the exact same key-value pairs
• findKey(object, callback): scans object and returns the first key for which callback returns a truthy value. If no key is found, returns undefined.
• findKeyByValue((obj, value): searches for a key on an object where its value matches a given value
• flatten(array): takes array with other arrays inside and returns a single-level array
• letterPositions(sentence): returns all the indices (zero-based positions) in the string where each character is found
• map(array, callback): returns a new array based on the results of the callback function
• takeUntil(array, callback): returns a slice of the array with elements taken from the beginning
• without(array1, array2): returns a subset array1, removing from it the elements from array2.
