@robbydhindsa/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 @robbydhindsa/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): takes in two arrays as parameters and uses eqArrays function to validate if the two arrays are equal to each other
• assertEqual(actual, expected): takes in two values as parameters and validates if the two values are equal to each other (uses '===')
• assertObjectsEqual(actual, expected): takes in two objects as parameters and uses eqObjects and eqArrays functions to validate if two objects have the exact same key:value pairs
• countLetters(sentence): takes in a string as a parameter and counts the number of times each character is used in the provided string
• countOnly(allItems, itemsToCount): takes in an array of strings (allItems) and an object specifying what to count (itemsToCount); returns the number of occurences of a particular string in allItems parameter
• eqArrays(array1, array2): returns a boolean value based on whether array1 and array2 are exactly equivalent
• eqObjects(object1, object2): returns a boolean value based on whether object1 and object2 are exactly equivalent
• findKey(obj, callback): takes in an object and a callback function as parameters; returns a particular key of the object, based on the callback function
• findKeyByValue(obj, val): takes in an object and a value as parameters; returns the specific key of the object (obj) that is equal to the value passed (val)
• head(arr): returns the first element of an array
• letterPositions(sentence): returns the index value of a particular character in a string
• map(array, callback): alters the array parameter based on the passed callback and returns the result
• middle(arr): returns the middle element(s) of an array
• tail(arr): returns all the elements of an array except for index 0
• takeUntil(array, callback): returns the elements of an array until the value of the callback is equivalent to an array, at which point it stops and returns that specific portion of the array
• without(source, itemsToRemove): removes specific elements of the array that is passed and returns the resulting array
