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 @k-j-t-w/lotide

Require it:

const _ = require('@k-j-t-w/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Asserts if given arrays are equal
• assertEqual(actual, expected): Asserts if given values are equal
• assertObjectsEqual(obj1, obj2): Asserts if given objects are equal
• countLetters(stringToCount): Returns a count of letters in a string (excludes spaces)
• countOnly(allItems, itemsToCount): Counts specified items in an object
• eqArrays(arr1, arr2): returns a boolean, true if arrays are equal, false if not
• eqObjects(object1, object2): returns a boolean, true if objects are equal, false if not
• findKey(object, callback): returns the key of a key value pair in an object depending on a callback
• findKeyByValue(objectToSearch, valueToFind): returns the key to the specified value of a specified object
• flatten(array): flattens an array (gets rid of nested arrays)
• head(array): returns the head head of an array (array[0])
• letterPositions(sentence): creates an object that stores letter positions for a given string
• map(array, callback): creates a new array with the callback function applied to every element
• middle(array): returns the middle of an array as an array, one element if array odd, 2 elements if array even
• tail(array): returns the tail of an array (an array that excludes the 0th element of the array)
• takeUntil(array, callback): returns a new array that takes elements of the source array until it hits a specified value (determined by the callback)
• without(source, itemsToRemove): returns an array that is the source array, but with specified elements removed (determined by itemsToRemoveArray)
