@sandeepgill62/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 @sandeepgill62/lotide

Require it:

const _ = require('@sandeepgill62/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): This function helps to test code.
• head(array): This function returns the first item in the array
• tail(array): This function returns the "tail" of an array: everything except for the first item (head) of the provided array.
• eqArrays(array1, array2): This function which takes in two arrays and returns true or false, based on a perfect match.
• assertArraysEqual(array1, array2, expected): This function which will take in two arrays and console.log an appropriate message to the console.
• without(source, itemsToRemove): This function which will return a subset of a given array, removing unwanted elements.
• flatten(array): This function which will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• middle(array): This function which will take in an array and return the middle-most element(s) of the given array.
• countOnly(allItems, itemsToCount): This function should take in a collection of items and return counts for a specific subset of those items
• countLetters(letters): This function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• letterPositions(sentence): This function which will return all the indices (zero-based positions) in the string where each character is found
• findKeyByValue(object, value): This function which 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.
• eqObjects(object1, object2): This function which will take in two objects and returns true or false, based on a perfect match.
• assertObjectsEqual(actual, expected): This function which will take in two objects and console.log an appropriate message to the console.
• map(array, callback): This function which will take in array and callback function. This function will provide the result with array according to callback function definition.
• findKey(object, callback): This function which will take in obejct and callback function. This function will provide the result with object according to callback function definition.
• takeUntil(array, callback): This function which will take in array and callback function. Each array element will check callback function if condition meets according to values.
