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 @dirtandgrass/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): compares two arrays and logs a message to the console
• assertEqual(actual, expected): compares two values and logs a message to the console
• assertObjectsEqual(obj1, obj2): compares two objects and logs a message to the console
• countLetters(str): returns an object with the count of each letter in the input string
• countOnly(allItems, itemsToCount): returns an object with the count of each item in the input array
• eqArrays(arr1, arr2): compares two arrays and returns a boolean
• eqObjects(obj1, obj2): compares two objects and returns a boolean
• findKey(obj, callback): returns the first key for which the callback returns a truthy value
• findKeyByValue(obj, value): returns the first key for which the value is found
• flatten(arr): returns a new array with all elements of the input array
• head(arr): returns the first element of the input array
• letterPositions(str): returns an object with the position of each letter in the input string
• map(arr, callback): returns a new array with the results of the callback function
• middle(arr): returns the middle element(s) of the input array
• tail(arr): returns a new array with all elements of the input array except the first
• takeUntil(arr, callback): returns a new array with elements of the input array until the callback returns a truthy value
• without(source, itemsToRemove): returns a new array with all elements of the input array except the ones to remove
