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 @brettg17/lotide

Require it:

const _ = require('@brettg17/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): tests whether two arrays are equal or not
• assertEqual(actual, expected): tests if a functions actual return is equal to the expected
• assertObjectEqual(actual, expected): test whether two objects are equal
• countLetters(chars): counts letters in a string
• countOnly(allItems, itemsToCount): checks how many times and item is in an array. returns undefined if not
• eqArrays(arrayOne, arrayTwo): tests to see if two arrays are equal
• eqObjects(object1, object2): tests to see if keys and values in an object are equal
• findKey(obj, callback): uses callback and returns true if truthy value is meant. if not return undefined
• findKeyByValue(genre, show): finds key by value. if value/key is not in the object return undefined
• countOnly(allItems, itemsToCount): checks how many times and item is in an array. returns undefined if not
• flatten(arr): takes an array with elements that include nested arrays. removes nested arrays creating a "flattened" array
• head(arr): returns first element of an array
• letterPositions(sentence): returns what position letters in a string are in.
• map(array, callback): map function returns an array based on the reults of the callback function
• middle(array): returns middle element of an array. middle two elements of even. empty array if two elements or less
• tail(arr): creates new array exluding first element in original array
• takeUntil(array, callback): return elements in an array up to the point truthy condition is met.
• without(source, itemsToRemove): whatever elements that are in first array but not in second will get pushed into new array.
