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 @bendhal/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): prints a message to the console declaring wether two arrays are entirely equal
• assertEqual(value1, value2): prints a message to the console declaring wether two values are entirely equal
• assertObjectsEqual(object1, object2): prints a message to the console declaring wether two objects have entirely matching key value pairs
• countLetters(string): counts the number of letters in a string
• countOnly(array, toCount): counts the number of times a specified entry shows up in an array
• eqArrays(array1, array2): checks if two arrays are entirely equal and returns true or false
• eqObjects(object1, object2): checks if two objects are entirely equal and returns true or false
• findKey(object, function): searches through an object and returns first key that returns a truthy answer to the callback function
• findKeyByValue(object, value): searches through an object and returns first key that has the specified value
• flatten(array): takes an array and finds any sub arrays and adds their elements to the main array subsequently removing said sub-array
• head(array): takes an array and returns the first entry
• letterPositions(string): creates an object that logs an array of indices for each letters position in the specified string
• map(array, callback): applies a callback to each element of an array and create a new array with the returned values of that callback
• middle(array): returns the middle elements of an array
• tail(array): returns every element of an array except for the first element
• takeUntil(array, callback): adds elements of an array to a new array until the callback returns falsey for an element
• without(array, itemToRemove): returns new array without specified item
