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 @lorrainec26/lotide

Require it:

const _ = require('@lorrainec26/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the first element from a given array.
• middle(array): returns an array contain the element at the middle position of a given array.
• tail(array): returns an array contain all the element from the given array except for the first element.
• countLetters(a string sentence): returns a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): returns an object contain only the specified item from all items.
• findKey(object, callback): scans the object and returns the first key for which the callback returns a truthy value; If no key is found, then it should return undefined.
• findKeyByValue(object, value): returns the key that has the same value as the given one.
• letterPositions(a string sentence): returns an object which stores letter as keys and their corresponding index as values.
• map(array, callback): returns a new array based on the results of the callback function.
• takeUntil(array, callback): collects items from the array until the callback is true and returns a new array.
• without(source, itemsToRemove): removes the specified items from a given array and returns a new array.
• assertArraysEqual(arrayOne, arrayTwo): logs assertion Passed/Failed for two arrays. It will return true for PASS and false for FAILED.
• assertEqual(actual, expected): logs assertion Passed/Failed for two items. It will return true for PASS and false for FAILED.
• assertObjectsEqual(actual, expected): logs assertion Passed/Failed for two objects.
• eqArrays(arrOne, arrTwo): returns true if two arrays are equal and false vice versa.
• eqObjects(obj1, obj2): returns true if both objects have identical keys with identical values. Otherwise, it returns false.
