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 @jhoangqm/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head: accepts an array and returns the first element
• tail: accepts an array and returns the same array but removes the first element
• middle: accepts an array and return only the middle element or elements
• countLetters: accepts a string and returns an object with the key value pairs of each character in a string, and the number of occurence
• countOnly: accepts an array of string and returns the count of specific subset
• findKey: accepts an object and a value: it will verify the object and returns the first key for which the callback function returns a truthy value
• findKeyByValue: searches for a key on an object that matches a given value
• flatten: given a single nested array, flattens into a single-level array
• letterPositions: returns all the indicators of each character in the given string
• map: iterates over given array and applies given callback function
• takeUntil: collects items from the provided array until the callback provided returns a truthy value
• without: returns an array after removing unwanted elements
• eqArrays: accepts two arrays and returns true or false based on if they are equal
• eqObjects: accepts two objects and returns true or false based on if they are equal
• assertObjectsEqual: Asserts strict equality of actual and expected objects
• assertEqual: Asserts strict equality of actual and expected input value
• assertArraysEqual: Asserts strict equality of actual array and expected array
