Lotide

A mini clone of the Lodash library.

Purpose

The purpose is to practice creating functions based on the Lodash library.

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 @andrewjhui/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(firArray, secArray, trueOrFalse): takes in two arrays and the value true or false to assess if they are the same array
• assertEqual(actual, expected): assess the primitive data types being equal to each other
• assertObjectsEqual(firObject, secObject, trueOrFalse): takes in two objects and the value true or false to assess if they are the same object
• countLetters(theBombString): counts the letters in the string, excluding spaces
• countOnly(allItems, itemsToCount): counts an array of strings and returns amount of times the string is shown in the array
• eqArrays(firstArray, secondArray): compares first array and second array
• eqObjects(object1, object2): compares first object and second object
• findKey(objectLookup, callback): takes in an object and takes in a callback function to find the key value within the object
• findKeyByValue(discoverObject, findValue): takes in an object and the key value. It should return the key that the value is found in the object.
• flatten(sneakyArray): uses recursive to flatten an array so that all nested arrays are in the top level array
• head(theArray): returns the first value in the array
• index: index of all the functions in lotide
• letterPositions(sentence): takes in a string and returns an object with all the letters with number of instances seen in the string
• map(array, callback): map returns a new array. it iterates through the old array and performs the callback function on the array.
• middle(findMiddleArray): outputs a new array with the middle numbers in an array.
• tail(theArray): takes the whole input array except first value of the input array
• takeUntil(array, callback): takes an input array and stops when it finds the value of callback
• without(theArray, removalArray): takes an input array and then removes all value from the array from the removalArray
