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 @mwilliamson.holmes/lotide

Require it:

const _ = require('@mwilliamson.holmes/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1,arr2): prints message after comparing two arrays
• assertEqual(actual, expected): prints a message comparing two values
• assertObjectsEqual(actual, expected): prints a message comparing two objects
• countLetters(string): takes in a string and returns an object with a count of each time the letters in that string occur
• head(array): returns the first item in an array
• tail(array): returns the "tail" of an array- everything except the first element (head)
• middle(array): returns the one middle element of an array with an odd number of elements, returns the middle two elements of an array with an even number of elements
• countOnly(allItems, itemsToCount): takes in a collection of items and return counts for a specific subset of those items
• letterPositions(string): returns an object with all the indices in the string where each character is found
• findKey(object, callback): scans the object and returns the first key for which the callback returns a truthy value
• findKeyByValue(object, value): given a value, search the object to find the first key associated with the property
• eqObjects(object1, object2): takes in two objects and returns true or false, based on a perfect match
• eqArrays(arr1, arr2): returns true or false that two arrays have the same values
• map(array, callback): return a new array based on the results of the callback function
• takeUntil(array, callback): return a slice of the array with elements taken from the beginning-it will keep collecting items until the callback returns truthy value
• without(source, itemsToRemove): returns a new array of all of the elements in the first array not included in the second array
