npm install @ajwadh/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): compare two arrays and prints out a message telling us if they match or not.
• assertEqual(arr1, arr2): compare two values primitive values and prints out a message telling us if they match or not.
• assertObjectsEqual(arr1, arr2): Takes in two objects and prints out whether they are equal or not.
• countLetters(sentence): Takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): It is given an array and an object. It will then return an object containing counts of everything that the input object listed.
• eqArrays(arr1, arr2): Takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(object1, object2): Takes in two objects and returns true or false, based on a perfect match.
• findKey(objects, 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.
• findByKeyValue(genreObject, movie): Searches for a key on an object where its value matches a given value and returns it.
• 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): Return 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 everything except for the first item (head) of the provided array.
• takeUntil(array, callback): Returns a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• without(source, itemsToRemove): Returns a subset of a given array, removing unwanted elements.
