@justin1002/lotide v1.0.1

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 @justin1002/lotide

Require it:

const _ = require('justin1002/lotide');

Call it:

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

Documentation

The following functions are currently implemented: input values are as follows: 1) arr = array 2) obj = object 3) str = string 4) callback = callback function

• head(arr): returns the first element in an array
• tail(arr): returns all elements after the first in an array
• middle(arr): returns the middle element of an array, returns two elements if the length is an even number
• eqObjects(obj1,obj2): returns a boolean value comparing two objects for equality
• eqArrays(arr1,arr2): returns a boolean value comparing two arrays for equality
• assertArraysEqual(arr1,arr2) assertion function that compares two arrays for equality
• assertObjectsEqual(obj1,obj2) assertion function that compares two objects for equality
• countLetters(str) creates an object which presents the letter(key) and the count(value)
• countOnly(arr,obj) creates an object that counts items in an array based on boolean keys-values an object
• findKey(obj,callback) returns the first key that matches the callback function requirements
• findKeyByValue(obj,key) returns the first key that matches the value in an object
• flatten(arr) takes an array with multiple dimensions and flattens to one dimension (only works with one additional dim)
• without(arr1,arr2) filters array 1 without items in array 2
• letterPositions(str) returns an object that shows the letter(key) and their relative index in an array
• takeUntil(arr, callback) returns an array that takes values until it reaches a certain condition from the callback
• map(arr, callback) returns an array that is mapped based on the callback function
