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 @cor23/lotide

Require it:

const _ = require('@cor23/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(inputOne, inputTwo): for asserting that two arrays are equal.
• assertEqual(actual, expected): compare two values, prints out a message if they match or not.
• assertObjectsEqual(actual, expected): takes in two objects and compares them, prints out a message if they match or not.
• countLetters(string): counts the letters in a given string, returns an object w/ letter count.
• countOnly(allItems, itemsToCount): reports back how many instances of each string in itemsToCount were found in the allItems array of strings.
• eqArrays(inputOne, inputTwo): takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(object1, object2): Returns true or false if both objects have identical keys with identical values.
• findKey(object, callback): takes in an object and a callback. returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue(object, value): takes in an object and a value, returns the first key which contains the given value, if no key with that given value is found, returns undefined.
• head(array): returns the first item in the array.
• letterPositions(sentence): returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callBack): returns a new array based on the results of the callback function.
• middle(array): takes in an array and returns the middle-most element(s) of the given array.
• tail(array): returns the "tail" of an array. everything except for the first item of the provided array.
• takeUntil(array, callback): keeps collecting items from a provided array until the callback provided returns a truthy value.
• without(source, itemsToRemove): returns a new array with only those elements from source that are not present in the itemsToRemove array.
