@jaylenpatterson/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 @jaylenpatterson/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): finds the first index of an array.
• tail(arr): Removes the first index of an array.
• middle(arr): Returns the middle number or numbers of an array of numbers.
• map(arr, callback): Performs a callback function on each index of an array.
• takeUntil(arr, callback): Removes a section of the array until the callback function finds the cut off point.
• findKey(obj, callback): Finds the object key pair that matches with the callback function.
• assertEqual(actual, expected): Assertion function that compares two values that aren't an object or string.
• flatten(arr): Returns a one dimensional array when passed an array of nested arrays.
• without(source, remove): Removes all items from source that are in the remove array then returns a new array.
• assertArraysEqual(arr1, arr2): Assertion function that compares two Arrays.
• findKeyByValue(obj, value): Finds the key of an object by inputting the value that corresponds to that key.
• letterPositions(str): Loops through an array, returns an object that contains each letter in the array and all of its index positions for every instance of that letter.
• countOnly(arr, obj):Loops through an array of true names and false names then returns a object that stores the amount of times each true name appears in the array.
• countLetters(str): Takes a string and stores all of its letters in an object. Returns a letter, number pair of each letter and all of its instances in the str.
• eqArrays(actual, expected): Checks if two arrays are equal.
• eqObjects(object1, object2): Checks if two objects are equal.
• assertObjectsEqual(actual, expected): Assertion function that compares two objects.
