A Complete Frontend Developer Textbook for Beginners (2023 Edition)
Exclusively on Medium

Music is the universal language of mankind. — Henry Wadsworth Longfellow
This textbook is published exclusively on Medium by Silicon Wat, an online Temple for coding Monks to achieve code Enlightenment! 😇
This first textbook corresponds to the first Udemy video course in a foundational trilogy that helps a complete beginner to become a well-rounded and future-proof Fullstack Engineer.
To keep up and stay current with the latest technologies, this entire trilogy is remastered every three years.

Preface
If you are a complete beginner aspiring to become a Frontend Engineer, this course is for you! Your only prerequisite is to signup for a free account on Codepen.
This course is different from other beginner’s courses in 8 unique ways:
1: HTML + CSS + JavaScript => Interrelationships Firstly, the three web languages (HTML, CSS, and JavaScript) are taught side-by-side in parallel. This approach may be three times harder, but it will deepen your understanding of their interrelationships, which the traditional way of learning them individually misses. Ample quizzes will be given to help you review everything you learn!
2: MDN Documentation => Modern + VanillaSecondly, the three web languages are taught in pure vanilla by referencing the most up-to-date documentation on the Mozilla Developer Network (MDN). This approach practiced by seasoned developers will expose you to the most modern syntaxes and browser APIs in great detail, such as HTML Semantics, CSS Flexbox/Grid, JavaScript ES6+, Geolocation, IndexedDB, Media Capture, Web Audio, Web Speech, Web Crypto, etc!
3: HTML/CSS/JavaScript => Data Structures + AlgorithmsThird, the three web languages are taught in relation to Data Structures and Algorithms. This mental model will help you develop a strong intuition of Computer Science fundamentals. Essentially, HTML is just a tree structure upon which CSS styles and JavaScript interactivity are applied through executing algorithms. With a solid and comprehensive foundation in these fundamentals, branching out to learn JavaScript-centric frameworks like React or Angular will be easy, if you so choose.
4: TDD Coding Exercises => Basic Music Theory ChallengesFourth, ample coding exercises will be provided to help you put into practice everything you learn. You will solve them in a way that closely mimics the actual process real developers follow. This process is called Test-Driven Development (TDD) and it gives developers a lot of flexibility to code in whatever way they like, so long as their code can get all the test cases to pass. To make these coding challenges fun for visual learners as well as auditory learners, the test cases will be musical in context! Of course, solutions and detailed explanations will be given for each problem.
5: HTML/CSS/JavaScript => Web ComponentsFifth, your new-found knowledge and skills culminate in building your own custom Web Components from scratch. They comprise of HTML Templates (for the HTML), Shadow DOM (for the CSS), and Custom Elements (for the JavaScript) — all of which are self-contained yet extensible and reusable. In other words, you will also learn how to share them across all your web pages and apps, and even avail them to other developers if you wish! Therefore, to create Web Components entails bringing together everything you learn about HTML, CSS, and JavaScript. As an example demo, we will use them to build a virtual piano that mimics all the functionalities of a real piano! In fact, your virtual keyboard can even interact with a real keyboard through a MIDI cable!

6: Web Components => Micro-FrontendsSixth, you will compose our Web Components into encapsulated web pages known as Micro-Frontends. This Frontend architecture divides up a large web app into smaller independent codebases, which in turn can be managed by many small independent teams. The result is greater agility for the individual developer and greater adaptability for the aggregate application. As such, the Micro-Frontend Architecture is a very popular choice for modern applications which are becoming increasingly larger and more complex. Furthermore, your Micro-Frontends will utilize Service Workers capable of connecting with the browser’s storage and external third-party APIs, making them behave almost like having backends unto themselves! In essence, your Micro-Frontends act just like native apps! By connecting your Micro-Frontends to a Machine Learning API, your virtual piano will be able to intelligently detect musical notes received by your microphone in real time! And to prove to you how totally awesome coding can be, your virtual piano will also be able to intelligently decipher musical sign language captured by your camera in real time too!

7: Micro-Frontends => Mobile/Desktop Native PWASeventh, you will learn how to combine and orchestrate your Micro-Frontends as a Progressive Web App (PWA) that meets all the performance requirements to be listed as a native app on the Google Play Store. In this course, you will build two Micro-Frontends: The first will be a music editor while the second will be music games. Your PWA will act as the parent container which seamlessly orchestrates the navigation and state management of its children Micro-Frontends. Furthermore, you will learn how to publish your PWA on the internet as a mobile and desktop app using your own custom domain and host it for free on GitHub Pages. And as an added bonus, you will also learn how to authenticate your users using the same cryptography that powers the Bitcoin and Ethereum blockchains!

8: Mid-Level Frontend Engineer => Jobs or GigsUnfortunately for self-taught developers, Junior positions are usually reserved for graduating college interns. Therefore lastly, by the end of the course, you will have mastered HTML, CSS, and JavaScript at the level of at least a Mid-Level Frontend Engineer to substantially improve your chance of getting hired for a full-time position. You will be more than ready to start practicing for your technical interviews, or you can work right away as an independent contractor to gain professional experience. Better yet, build an app for your very own startup! 😎
