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 @stella-zb/lotide

Require it:

const _ = require('@stella-zb/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head: returns the first item in the array
• tail: returns the "tail" of an array: everything except for the first item (head) of the provided array
• middle: take in an array and return the middle-most element(s) of the given array
• assertArraysEqual: take in two arrays and console.log an appropriate message to the console
• assertEqual: compare the two values it takes in and print out a message telling us if they match or not.
• assertObjectsEqual: take in two objects and console.log an appropriate message to the console
• countLetter: count letter in a string
• countOnly: take in a collection of items and return counts for a specific subset of those items
• eqArrays: takes in two arrays and returns true or false, based on a perfect match
• eqObjects: take in two objects and returns true or false, based on a perfect match
• findKey: take in object & callback, scan object, return first key for which callback return a truthy value // return undefined if no key is found
• findKeyByValue: takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined
• flatten: take in an array of arrays and return a "flattened" version of the array
• letterPosition: return all the indices (zero-based positions) in the string where each character is found.
• map: return a new array based on the results of the callback function
• takeUntil: keep collecting items from a provided array until the callback provided returns a truthy value
• without: return a subset of a given array, removing unwanted elements
