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 @sanderevans/lotide

Require it:

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

Call it:

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

• tail(array): Returns everything but the first element of an array.
• middle(array): Returns the middle element(s) of an array.
• assertArraysEqual(array1, array2): Print whether two arrays are equal.
• assertEqual(val1, val2): Print whether two primitives are equal
• assertObjectsEqual(object1, object2): Print whether two objects are equal.
• countLetters(string): Returns an object counting the occurrances of each character in a string excluding spaces.
• countOnly(allItems, itemsToCount): Returns an object listing the occurances of specified elements in an array.
• eqArrays(array1, array2): Returns whether two arrays are equal recursively.
• eqObjects(object1, object2): Returns whether two objects are deeply equal.
• findKey(object, callback): Returns the object key which fulfills the callback filter.
• findKeyByValue(sourceObject, keyValue): Returns the object key which matches a value.
• flatten(array): Returns an array with all elements of the given 2D array and their contents placed into a single one-dimensional array.
• letterPositions(string): Returns an object listing all indexes of each character in a string.
• map(array, callback): Executes a callback function for each element of an array.
• takeUntil(array, callback): Returns an array containing each element of an array before the first element which fulfills a callback filter.
• without(sourceArray, itemsToRemove): Returns an array with all instances of the requested elements removed.
