By @alesanchezr and other contributors at 4Geeks Academy

This tutorial its part of a bigger group of tutorials about web development, this repository focuses only on Javascript Events, you will learn Mouse Events, Keyboard events, Frame Events and how to react to those events to make your web application interactive.

What you will learn during this tutorial:

1. The first event that triggers on a website
2. make your code react to user clicks on buttons
3. Make a counter that increases when the user clicks
4. Add event listeners
5. What is the event target?

5. Using events & The DOM ← you are here now 🔥
6. Object Oriented Programming

One click installation:

Local Installation

1. Make sure you have learnpack installed and node.js version v14+ and jest v27. This is the command to install the learnpack-cli and jest:

$ npm i learnpack jest@27.0.6 -g

2. Clone or download this repository. Once you finish downloading, you will find a new folder with a subdirectory "exercises" that contains all the exercises within.

3. Install the learnpack plugin to test and compile vanillajs:

$ learnpack plugins:install learnpack-dom

4. Start the tutorial/exercises by running the following command from the root of the project:

$ learnpack start

How are the exercises organized?

Each exercise is a small react application containing the following files:

1. app.js: represents the entry python file that will be executed by the computer.
2. index.html: represents the entry website.
3. style.css: your website styles, they have to be imported from the index.html
4. README.md: contains exercise instructions.
5. test.js: you don't have to open this file, it contains the testing script for the exercise.
