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 @devlhalpin/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr) : Returns first element of array tail(arr) : Returns array minus the first element middle(arr) : Returns middle of array assertEqual(value1, value2) : Returns if value1 is equal to value2 assertArraysEqual(arr1, arr2): Same as assertEqual but takes arrays as arguments assertObjectsEqual(obj1, obj2): Same as assertEqual but takes objects as arguments eqObjects(obj1, obj2): Used by assertObjectsEqual to test objects are the same eqArrays(arr1, arr2) : Used by assertArraysEqual to test arrays are the same flatten(arr): Flattens array with nested elements countLetters(str): Returns object using letters in provided string as keys and number of occurences of each letter as values countOnly((arr, obj): Returns object using array values as keys and number of occurences of each key as values findKey(obj,callback): Returns first key that matches callback in object findKeyByValue(obj, value): Returns first key whose value matches value in object letterPositions(str): Returns object with each letter in string as key and it's indexes as values map(array, callback): Returns array with the results of calling callback on every element in the provided array takeUntil(array, callback): Returns array containing all elements of provided array up until the index value matches the results of callback without(arr1, arr2): Returns array containing all elements that are in arr1 and not in arr2
