Build anything you want with JavaScript
Have you tried learning JavaScript for a while now, but feel that you’re not making progress?
You went through many resources, but you still cannot understand JavaScript.
You’ve read through all the free resources you can find. You tried:
- Googling for web development articles
- Using beginner websites like CodeAcademy
- Going through FreeCodeCamp
- Reading books other developers recommend
You may have spent some money on learning JavaScript too.
- You bought books and courses.
- You may even have spent $12,000 on a Bootcamp.
Each resource helped you understand some JavaScript, But you still can’t piece everything together — you don’t know how to build things from scratch
When you try to code something from scratch, you freeze at a blank JavaScript file
You twiddle your thumbs as you stare into the JavaScript file, but nothing comes to mind. You don’t know how to start.
You realize one thing — you don’t know JavaScript.
It’s frustrating, but you acknowledge there’s a gap in your knowledge.
You lack confidence in JavaScript
So you avoid JavaScript whenever you can. You rely on HTML and CSS — even resorting to hacky practices to avoid JavaScript.
This lack of confidence in JavaScript makes you nervous. You’re so nervous about JavaScript, you screw up on your interviews.
This lack of confidence also affects you on the job too:
- You don’t dare to say “yes” when you’re asked to use JavaScript.
- But you don’t want to say “no” either.
You rely on Google when you need JavaScript
You look for libraries and plugins others have created. You hope they work, but you’re screwed if they don’t.
You copy-paste answers from Stack Overflow and various blogs you read. And you can’t understand what you copied.
You’re worried about being called out as a fraud.
Deep down inside, you want think like a developer
If you know how to think like a developer, you can build anything you want! Nothing can stop you from building things:
- You won’t freeze up
- You know exactly how to start and how to improve as you go along
- Even if you get stuck, you can get yourself unstuck easily without Googling all the time.
You can solve any problem you encounter with JavaScript.
It’s a superpower.
Thinking like a developer is simple. But it’s not easy. There are four steps:
- Identify the problem you need to solve
- Break the problem down into smaller problems
- Solve each small problem
- Assemble your solutions into the final solution.
The hardest part is knowing how to break large problems down into smaller problems
Learn to build anything you want with JavaScript

Hello, I’m Zell!
I taught myself how to code without any prior programming experience.
I managed get a $100,000 yearly income within my first few years — freelancing — only with my HTML, CSS, and JavaScript skills.
Since then, I helped over one million people become better frontend developers through my blog and courses.
Today, I’m here to help you learn JavaScript.
Zell has been featured in:
Zell’s work is detailed and not overwhelming. He guided me step-by-step, from basics to advanced concepts. He ensured I understood everything before going deeper.
Thanks to Zell, I got a frontend job in Switzerland!

Pierre Wizla
You want to build beautiful, interactive, and crazy things.
I started off making simple HTML and CSS sites. There was nothing fancy about them.
As I learned to think like a developer, I began building crazy things I couldn’t imagine building before. For example:
- A custom calendar widget for a boutique hotel
- A static site generator that ran my blog for a while
- Interactive components with cool animations
I want to show you an example of an interactive component. Here’s a modal animation I built. It brings a smile to my face whenever I see it 🤗.
Another example: I built this component where you can preview artwork on a wall. You can then switch between different furniture scenes to get a sense of how the artwork looks.
Pay attention to two things in this example:
- Watch how the artwork zooms into the furniture setting
- Watch how the furniture switch as we change scenes
Pretty cool, yeah?
You don’t need a Computer Science degree to learn JavaScript
I used to suck at JavaScript. I rather write hacky CSS than use JavaScript — even for simple components like a menu.
I thought it was impossible for me. I thought I was too old, I didn’t have a Computer Science degree, I wasn’t smart enough.
Turns out I was wrong.
You can learn JavaScript without a Computer Science degree. You can even have a successful career in software without a Comupter Scrience degree.

JavaScript is simply one step in the entire process of becoming a good developer.
Have faith in yourself — even if you tried many things but failed — because you can do it. I know how to help you learn JavaScript. I’ve been through the process myself and I taught many students via this course.
Here’s the best way to learn JavaScript
When I teach JavaScript, I focus on a two-step process that’s proven to work:
- I help you understand JavaScript concepts
- You learn to apply these concepts by building real things
I help you understand concepts by turning abstract concepts into simple everyday examples. These analogies have helped many students understand JavaScript concepts.
For example:
- When I teach functions, I ask students to imagine drawing water from a well.
- When I teach if/else statements, I ask students to imagine crossing the street at a traffic light.
- When I teach for-loop, I ask students to imagine bouncing a ball.
- When I teach scopes, I ask students to imagine a one-way glass.
Once you understand the concept, I teach you how to use them in real projects, which cements the knowledge into your subconscious, and you’ll always know (and remember) what to do.
Zell makes JavaScript fun and easy to learn. He explains technical jargon with everyday life examples. These examples make me curious and excited to learn every day!
Now, I no longer panic when I use JavaScript. I know I can learn it.

I thought the price seemed a little high at first but I always found Zell’s content informing and easy to understand so I bought the course, and I’m glad I did!
The content in Learn Javascript is easy to understand and laid out in a way that builds in the areas you need to know for web development fundamentals. Even for an industry veteran like myself, I’ve found that knowing the fundamentals is most important, regardless of what framework you decide to work in.
I highly recommend taking this course whether you’re starting out or already experienced in Javascript.

Learn to build 20 components
Learn to build practical components you use at work — you get to:
- Understand how each component works
- Build them from scratch (without frameworks or libraries)
- Tweak them so you improve their usability and accessibility.
We’ll cover each component step-by-step — even if the difficulty of components rises as you go thorugh the course.
Here are the 20 components you'll build:
- Off-canvas Menu
- Modal Window
- Accordion
- Tabbed Component
- Carousel
- Calculator
- Popover
- Todolist
- Typeahead
- Datepicker
- Countdown Timer
- Google Maps Clone
- Dota Heroes Page
- Auto-hiding Sticky Nav
- Slide & Reveal
- Infinite Scroll
- Spinning Pacman
- Drag and Drop
- A Tiny Framework
- Dota Heroes SPA
Here's a sneak peek of the components:
Learn JavaScript showed me a clear path to learn JavaScript. It integrated theory into real-life projects and helped me stay focused and motivated.
I feel more confident about my JavaScript skills and I’m no longer afraid to show my work at job interviews.

Ion Leahu
Written to help you learn
I have a bold aim for Learn JavaScript — When you complete the course, you can build anything you want from scratch without Googling for answers.
You will understand JavaScript no matter what level you’re at.
I improved the lessons over and over based on past students’ experiences. You’ll learn the right things in the right order. I’m here to ensure you have the best possible experience with JavaScript.
Learn JavaScript takes you through all the steps in building the components. The course doesn’t stop after the first steps. It shows you how to improve the component and include best practices.
This is something I found so hard to learn from other courses. I finally started to understand how to move on from a beginner level to an intermediate level.

Reviews from students who joined Learn JavaScript
Learn JavaScript empowered me as a frontend developer. I went from knowing nothing about JavaScript to building a custom design system for my company entirely in JavaScript. What’s more, each component I build is also accessible thanks to Zell’s accessibility lessons.
This the best course to learn JavaScript quickly. It is super practical, we get to build actual components we see and interact in the browser everyday, unlike most courses which go into abstract uses of JavaScript. Learn JavaScript is also very easy to understand.
Now, I know how build my own components. I know how to start, how to code it up, and how to search for (and understand) the parts that I don’t know yet. This course gave me the confidence to call myself a front-end developer.

Mark Teekman
Zell explains things in a way that no other instructor has been able to do in my 15+ years of trying to “self educate” in the world of Javascript.
In this course, Zell integrates every piece of JavaScript theory into building real UI. He shows you how to build simple things, then how to refactor the code with useful modern techniques.
Learn JavaScript helped increase my confidence at JavaScript. I’ve since refactored our style guide at work to completely remove jQuery. I also have the confidence to start a Vue project.

Joshua Briley
I wasn’t sure if Learn JavaScript was going to be any different from other JavaScript courses out there. But Zell proved me wrong.
Learn JavaScript is the ONLY course that helped me understand JavaScript. It explains JavaScript in depth with lots of examples. It also helped me learn to think like a developer.
Now, I can build some applications myself, I can understand other developers’ code, and I can give answers to questions on Stackoverflow.

Adam Ragheb
Learn JavaScript is the best and most helpful JavaScript course I found.
I used to think that JavaScript is overwhelming and hard. This course breaks JavaScript into doable chunks. Each lesson is clear and concise. I don’t feel overwhelmed or confused as I go through them.
I gained the confidence that I can not only understand JavaScript, but I can master it.

Jesse Mcintire
I love the step-by-step structure in Learn JavaScript. I also love the text-based approach to lessons. They helped me understand and internalise JavaScript instead of feeling “I just watched some videos”.

Dave Henson
Learn JavaScript is the best way to learn JavaScript. I never found anything like it out there. It starts all the way from the beginning. And it shows you understandable code examples all the way through.
The course pushed me forward in my coding career. JavaScript became fun to write. I no longer avoid JavaScript.

Robert Mittl
Learn JavaScript helped me discover holes in my knowledge even though I have a few years of JavaScript experience!
I understood JavaScript much better than before. I became more confident when working with frameworks and libraries, and I spend less time on Google and Stack Overflow

Oriol Gasquez
Most courses out there aren’t very beginner friendly. They assume you already know some stuff and they just zip through things with little or no explanation. But Learn JavaScript doesn’t.
I loved the way things are presented in Learn JavaScript. The explanations are very clear. This course makes it very easy to learn with the examples and source code provided.
I haven’t finished the entire course yet, but I would recommend it. It has been excellent so far.

Tim St-john
Learn JavaScript is easy to follow. Zell seems to knows what people struggle with. He uses examples to demonstrate concepts. And as far as I know, Zell is the only instructor that you can email and get a timely answer.
I’m able to learn faster compared to other methods I tried. And now, I am able to complete Codewars challenges.

Erik Schjolberg
This is the first course where I learned to differentiate which parts of JavaScript are important and which parts are not.
I used the knowledge I learned to create real components. It’s very satisfying to see my code doing something of real and practical use.
