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

npm install @metaphive/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): Retrieves the first element of an array.
• tail(arr): Retrieves all other elements except the head.
• middle(array): Takes in an array and returns the middle-most elements.
• flatten(array): Takes in an array of arrays and returns a single array.
• findKeyByValue(obj,objVal): Takes in an object and a value. It should scan the object and return the first key which contains the given value.
• findKey(ObjectToTraverse,Callback): Takes in an object and a callback. It will traverse the object and return the first key for which the callback returns a truthy value. If no key is found, then it will return undefined.
• eqArray(array1,array2): Takes in two arrays and returns a true or false value.
• countOnly(allItems,ItemsToCount): Takes in an array of strings and returns an object with the appropriate counts.
• countletters(phrase): Takes in an array of strings and returns an object with the unique letter count.
• letterPositions(phrase): returns all the indicies in the string where each character is found.
• assertObjectEqual(array): Takes in two objects and console.log(s) an appropriate message based on the result.
• assertEqual(array): Takes in two values and prints a message to the console indicating if there was a match or not.
• assertArraysEqual(actual,expected): Takes in two arrays and logs the appropriate message.
• without(source,itemsToRemove): Takes in an array and itemsToRemove returning a subset of a given array, removing unwanted elements.
• takeUntil(newArr,callback): Takes in an Array and a Callback, returns a slice of the array taken from the beginning until the callback function returns a truthy value.
• map(array,callback): Takes in an array and a callback and returns a new array based on the results of the callback function.
• eqObjects(Object1,Object2): Takes in two objects and returns true or false, based on a perfect match.
