Learn The DOM Interactively

By @alesanchezr and other contributors at 4Geeks Academy

This tutorial is part of a bigger group of tutorials about web development, this repository focuses only on The DOM.

You will learn the following concepts:

1. How to select elements from your website

2. Manipulate them with Javascript (change styles, add event listeners).

3. Remove elements programmaticall.

4. Change your entire website without a refresh.

I strongly recommend doing this the tutorials in this order:

1. Introduction to HTML
2. Introduction to CSS
3. Introduction to Javascript
4. Introduction to The DOM ← you are here now 🔥
5. Using events & The DOM
6. Object Oriented Programming

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 vanillajs website containing the following files:

1. index.js: represents the entry javascript file that will be executed when the website loads.
2. index.html: represents the HTML entry for 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.
