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 @saba072/lotide

const _ = require('@saba072/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual: This function will compare the two values it takes in and print out a message telling us if they match or not.
• head: This function will return the first item in the array.
• tail: This function will return the "tail" of an array: everything except for the first item (head) of the provided array.
• eqArrays: This function will take in two arrays and returns true or false, based on a perfect match.
• assertArraysEqual: This function will take in two arrays and console.log an appropriate message to the console.
• without: This function will return a subset of a given array, removing unwanted elements.
• flatten: This function will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• middle: This function will take in an array and return the middle-most element(s) of the given array.
• countLetters: This function will take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• letterPositions: This function will return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue: This function will 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.
• eqObjects: This function will take in two objects and returns true or false, based on a perfect match.
• assertObjectsEqual: This function will take in two objects and console.log an appropriate message to the console.
• takeUnit: This function will keep collecting items from a provided array until the callback provided returns a truthy value.
• findKey: This function will take in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• countOnly: This function will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• middle: This function will find the middle values in an array
