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.

npm install @amnah/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Returns the first value of an array
• tail(array): Returns all the values of an array after the first value
• middle(array): Returns the middle value of an array
• without(source, itemsToRemove): Returns a subset of an array, removing the unwanted elements
• takeUntil(array, callback): Will keep collecting items from a provided array until the callback provided returns a truthy value
• map(array, callback): Returns a new array based on the results of the callback function
• letterPositions(sentence): Returns all the indices (zero-based positions) in the string where each character is found
• findKey(object, callback): Takes 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
• findKeyByValue(obj, value): Takes 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
• eqObjects(object1, object2): Takes in two objects and returns true or false, based on a perfect match
• eqArrays(array1, array2): Takes in two arrays and returns true or false, based on a perfect match
• countOnly(allItems, itemsToCount): Returns a proper report (an object) on all the strings found in the input array, and their respective counts
• countLetters(sentence): Takes a sentence (as a string) and then returns a count of each of the letters in that sentence
• assertObjectsEqual(actual, expected): Takes in two objects and console.logs an appropriate message to the console
• assertArraysEqual(array1, array2): Takes in two arrays and console.logs an appropriate message to the console
• assertEqual(actual, expected): Prints to the console, when an expected outcome fails
