@johnarvi/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 @johnarvi/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Logs a message to show whether 2 arrays match.
• assertEqual(x,y): Logs a message to show whether 2 primary objects match.
• assertObjectsEqual(Obj1, Obj2): Logs a message to show whether 2 objects match.
• countLetters(string): returns the count of each letter of the string with an Object format.
• countOnly(allItems, itemsToCount): returns the number of times a value (itemsToCount) appears in an array
• eqObject(object1, object2): compares tow objects and returns a bollean if the values are the same and the number of keys are the same. This currently does not work on nested objects- to be implented at a later date
• eqArrays(arr1,arr2): compare 2 arrays and return true if they’re equal. This currently does not work on nested arrays- to be implented at a later date
• findKey(obj1, callback): returns the first key which matches the value which is given by the callback.
• findKeyByValue(object, value): returns the first key which matches the value. (This is with no callback function).
• flatten(array): Takes in a potentially nested array and spreads it to a single-nested array.
• head(array): returns the front of the array.
• letterPositions(sentence): returns an object that contains the letters (key) and index positions (value) of the sentence
• map(array, callback): takes in two arguments 1) array to map and 2) callback function (when predicate is met) should return the altered array
• middle(array): returns a new array with the middle index value/s of the original array
• tail(array): returns a new array without the first index value of the original array
• takeUntil(array, callback): takes a slice of an array with index values taken from the beginning until callback/predicate returns a truthy value
• without(source, itemsToRemove): returns an array without the specified items
