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 @dlaserna/lotide

Require it:

const _ = require('dlaserna/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(...): Asserts if two arrays compared are equal.
• assertEqual(...): Asserts if two values compared are equal.
• assertObjectsEqual(...): Asserts equality of two compared objects.
• countLetters(...): Creates an object with the letter so the string parameter as keys and the number of those letters as values.
• countOnly: Takes an array and counts only those specified values of the array.
• eqArrays(...): Asserts if two compared arrays are equal.
• eqObjects(...): Asserts if two compared objects are equal.
• findKey(...): Scans object and returns first key for which callback returns truthy. If no key found, function returns undefined.
• findKeyByValue(...): Scans an object and returns first key that has a specified value. If no key found, function returns undefined.
• flatten(...): Takes nested arrays and converts into a single array.
• head(...): Return the first element of an array.
• letterPositions(...): Returns an object locating the index of each value in a string.
• map(...): Takes to parameters, an array and function that modifies the array. Returns modified array.
• middle(...): Returns an array of the middle value of an array. If length of the array is even, returns an array of the two middle values.
• tail(...): Returns the sliced elements from index 1 onwards.
• takeUntil(...): Takes two parameters: an array and a callback function. Returns a slice of array with elements taken from the beginning. Will keep going until callback returns a truthy value.
• without(...): Takes two arrays as parameters: a source and an item to remove. Returns an array that excludes the items removed.
• function3(...): description
