@kinetics11/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 kinetics11/lotide

Require it:

const _ = require('kinetics11/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Compares the equality of two arrays
• assertEqual(actual, expected): Compares two values, and the expected result of a function
• assertObjectsEqual(actual, expected): Compares two objects for equality, and the expected result
• countLetters(string): Returns the number of letters in a string
• countOnly(allItems, itemsToCount): Takes in a collection of items and return counts for a specific subset of those items
• eqArrays(arr1, arr2): Loops through two arrays to check for equality
• eqObjects(object1. object2): Takes in two objects and returns true or false, based on a perfect match
• findKey(obj, callback): Scans the object and returns the first key in which the callback returns a truthy value. Will return undefined if no key is found
• findKeyByValue(object, value): Scans the object and returns the first key that contains the given value. Will return undefined if no key with the given value is found
• head(array): Returns the first item in the array
• letterPositions(sentence): Takes a sentence and returns the index of each letter within the sentence
• map(array, callback): Creates a new array that has the results of calling a function on each element of the input array (an alternative to the Array,prototype.map() method)
• middle(arr1): Returns the middle index element(s) of an array
• tail(array): Returns all items except for the first item of the array
• takeUntil(array, callback): Returns elements from an array until the callback provided returns a truthy value
• without(arr1, exclude): Returns a new array excluding the specified unwanted elements
