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 @username/lotide

Require it:

const _ = require('@nick.maniutin/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the first element of an array
• tail(array): returns all elements except the head
• middle(array): returns the middle (s) of an array
• flatten(array): takes in an array of arrays and returns a single array
• findKeyByValue(object, value): scans the object and returns the first key which contains the value
• findKey(object, callback): traverses the object and return the first key for which the callback returns a truthy value.If no key is found, it returns undefined
• eqArrays(array1,array2): compares two arrays
• countOnly(allItems,itemsToCount): takes in an array and returns an object with the appropriate counts
• countLetters(sentence): counts specified letter in a string
• letterPositions(sentence): returns all the indicies in the string where each character is found
• assertObjectsEqual(actual, expected): asserts comparison of two objects
• assertEqual(actual, expected): asserts two values
• assertArraysEqual(actual,expected): asserts comparison of two arrays
• without(source, itemsToRemove): returns a subset of a given array, removes unwanted elements
• takeUntil(array, callback): returns a slice of the array taken from the beginning until the callback function returns a truthy value
• map(array, callback): returns a new array based on the results of the callback
• eqObjects(object1, object2): compares two objects
