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 studies at Lighthouse Labs.

Usage

Install:

npm install @wjb8/lotide

Require it:

const _ = require('@wjb8/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arrayOne, arrayTwo): compare two arrays and return true if equal
• assertEqual(actual, expected): return true if actual === expected
• assertObjectsEqual(obj1, obj2): compare two objects and return true if equal
• countLetters(string): return an object of letters and their occurences in the string
• countOnly(allItems, itemsToCount): returns an object of only the items listed in the second parameter
• eqArrays(arrayOne, arrayTwo): used with assertArraysEqual to compare two arrays
• eqObjects(obj1, obj2): used with assertObjectsEqual to compare two objects
• findKey(obj, callback): returns keys in an object that match the callback function result
• findKeyByValue(object, val): similarly returns key that holds the passed value argument
• flatten(array): returns a new array of all elements in the passed array ignoring nested arrays
• head(array): returns the first element of an array
• letterPositions(sentence): returns the positions in the string of the passed letter
• map(array, callback): executes a callback function on each element of the array and returns a new array of the results
• middle(array): returns the middle element of an array (middle two elements if odd)
• tail(array): returns the array with the head removed
• takeUntil(arr, callback): returns elements in the array until the callback function returns false
• without(source, itemsToRemove): returns new array without the list of items to remove
