@kaz1022/lotide v1.0.0

Lotide

A mini clone of the Lodash library.

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 @kaz1022/lotide

Require it:

const _ = require('@kaz1022/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Checking to see if your array output and the expected array output is the same.
• assertEqual(actual, expected): Checking to see if your actual output and the expected output is the same.
• assertObjectsEqual(actual, expected): Checking to see if your actual object output and the expected output is the same.
• eqObjects(object1, object2): Checking to see if object1 and object2 is the same.
• eqArrays(arrayOne, arrayTwo): Checking to see if arrayOne and arrayTwo is the same.
• countLetters(strings):The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(strings):The function will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• findKeys(objects, callback):The function 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(anObj, value):The function takes in 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.
• flatten(array):The function takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• letterPositions(sentence):The function will return all the indices (zero-based positions) in the string where each character is found.
• head(array):The function returns the first item in the array.
• tail(array):The function returns the "tail" of an array: everything except for the first item (head) of the provided array.
• middle(array):The function takes in an array and return the middle-most element(s) of the given array.
• map(array):The function takes in two arguments: An array to map, A callback function. The map function will return a new array based on the results of the callback function.
• takeUntil(array, callback):This function will keep collecting items from a provided array until the callback provided returns a truthy value.
• without(source, itemsToRemove):This function will return a subset of a given array, removing unwanted elements. It returns a new array with only those elements from source that are not present in the itemsToRemove array.
