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 @khanduulga/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): checks if both arrays are equal
• assertEqual(actual, expected): checks if the primitive values are equal
• assertObjectsEqual(actual, expected): checks if both objects are equal
• countLetters(string): returns an object with each key being a letter from given string and its value being how many times the letter occured
• countOnly(allItems, itemsToCount): returns an object given a list, count only the items indicated by the itemsToCount object (eg. {'hello': true, 'hi': false})
• eqArrays(actual, expected): checks if both arrays are equal, returns a boolean
• eqObjects(actual, expected): checks if both objects are equal, returns a boolean
• findKey(object, callback): returns the first key the callback returns a truthy value for
• findKeyByValue(object, value): returns the first key that holds the given value
• flatten(array): given an array, returns the array in a linear fashion going only 2 levels deep.
• head(array): returns the first element in the array
• letterPositions(string): given a string returns an object with each letter being a key and its value being a list of the string indicies which the letter occurs on.
• map(array, callback): given an array and a callback, returns a new array after the callback is implemented to each item
• middle(array): returns a list of the middle item(s) in the given list thats >=3 in length
• tail(array): returns a list of the rest of the array without its head (or first element)
• takeUntil(array, callback): returns a slice of the given array until the callback returns a truthy value
• without(array, remove): given a remove array, returns the given array without elements that are the same as in the remove array
