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 @charleysmithschofield/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: a function that compares two arrays for equality.
• assertEqual: is a function that compares two values for equality.
• assertObjectsEqual: is a function compares two objects for equality.
• countLetters: is a function that takes in a string and returns a count of each of the letters in that string.
• countOnly: is a function that takes in a collection of items and counts the occurences of specific items.
• eqArrays: is a function that takes in two arrays and returns true or false, based on a perfect match.
• eqObjects: eqArrays takes in two objects and returns true or false, based on a perfect match.
• findKey: is a function that takes in an object and a callback and return the first key for which the callback returns a truthy value.
• findKeyByValue: is a function that takes an object and a value as inputs and returns the first key in the object that has that value.
• flatten: is a function that takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• head: is a function that will return the first element of an array, also known as the "head".
• letterPositions: is a function that returns all the indices (zero-based positions) in the string where each character is found.
• map: is a function that takes in an array and a callback and reuturns a new array based on the results of the callback on each item in the array.
• middle: is a function that finds the middle elements of an array.
• tail: is a function which returns the "tail" of an array. The "tail" is everything except for the first element.
• takeUntil: is a function which returns a "slice of the array with elements taken from the beginning".
• without: is a function that returns a subset of a given array, removing unwanted elements.
