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 @seunsoetan/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function head(array): returns the head - (first element) in an array.
• function middle(array): returns the middle element of an array.
• function countOnly(allItems, itemsToCount): allItems: an array of strings that we need to look through. itemsToCount: an object with items/strings to count as key and a boolean value (true or false) that specify is to count the item in the allItems array.
• function eqArrays(array1, array2): returns true if both arrays are identical.
• function eqObjects(object1, object2): returns true if objects(objects could contain arrays or primitive values) are equal and identical.
• function findKey(object, callback): A higher order function findKey that returns the first key in the object that satisfy the condition in the callback and returns a truthy value.
• function findKeyByValue(inputObject, value): find the key in an object by its value.
• function map(array, callback): A higher order function map that takes an array and any callback function and returns a new array of the results of the callback function.
• function takeUntil(array, callback): A higher order function - takeUntil that returns an array of elements from the beginning of the array to the item that satisfies the callback's truthy value returned as output.
• function without(sourceArray, itemsToRemoveArray): function without that takes an array and a list of items and returns the array without the items in itemsToRemoveArray.
• function assertEqual(actual, expected): custom assert function to test that primitive output from a function(actual) is equal to the expected(also a primitive value).
• function assertArraysEqual(actualArray, expectedArray): custom assert function to test that array output from a function(actual) is equal to the expected(also an array).
• function assertObjectsEqual(actualObject, expectedObject): custom assert function to test that object output from a function(actual) is equal to the expected(also an object).
