There is no formation without repetition.

So, you've done a few courses and read a few books but still don't feel great about your relationship with JavaScript.

How do you get better?

Build things. Lots of things. Build 1,000 things. Keep it up and don't stop. Seriously.

This has always been my advice. Just put in the work and you will get better.

But Wes, what should I build? I have no ideas! Please don't make me do another todo app.

Ideas, Eh? I've got lots! This is JavaScript30 — let's build 30 things together.

Who is this For?

Beginner to Intermediate developers and designers who want to become comfortable with both JavaScript fundamentals and working in the DOM without a library.

You should already know some JavaScript to start - This isn't a JavaScript 101 course. We learn by application - encountering many new situations while talking about the hows, the whys and the whats that we use to solve them.

We steer clear of opinionated design patterns, frameworks, libraries and any type of abstraction. These things are great and often needed, but can obstruct learning and constrain initial understanding.

These tutorials rely heavily upon browser APIs, most of which involve interaction with the page. If you are stuck in console.log() land, these videos are your next step. Oh, the stuff we build is really fun!

Wes, How is this Free?

These videos are free as a thank-you to everyone who has supported my premium courses as well as because I believe in giving back to the community. I see a huge need for these videos and I really think it will help many of you become comfortable creating with JavaScript.

While I've spent over 300 hours on JavaScript30, enough people find they really click with my teaching style and continue their learning with one of my premium courses. It all works out!

FAQ

What font / color scheme / editor / terminal is that?

I answer everything over at wesbos.com/uses. Feel free to tweet me any more questions!

I have a question, can I email you?

While I'd absolutely love to help everyone out, there are 120,822 people taking this course. I hope to get a forum setup sometime soon. If you are a member of one of my premium classes, you can jump into the #JavaScript30 room in our Slack channel.

I found another way! Could it be?!

Yes! There are probably 100 different ways to solve each of these exercises, if your answer doesn't line up with mine, it means you did a really good job at trying to figure it out yourself. My answers are by no means the best answers - just a single way of doing it. Instead of emailing me - write a blog post about how you did it. Share what you know!

I lost, deleted or never got my welcome email! What do I do?

Log into your account, or create an account with the same email you used to get the series.

Your CDN for the videos is blocked in China :(

Don't worry, I learned Chinese and uploaded to Baidu. Download them here.

Can I host a meetup / study group? Can I stream these in my classroom? Can I arrange a playing?

Yep yep yep - as long as you do not redistribute the videos you are welcome and encouraged to do this.

Can I re-distribute these and then charge money for them?

I can't believe I have to make this a FAQ. No, you silly goose.

Will these be on YouTube too?

I will release one per week over the next 30 weeks on YouTube. You can get them all right now if you sign up.

I found a typo or errata

If it's a typo on the site, please shoot me an email here. If it's a correction in the code, you can submit those via GitHub! Please see the above FAQ if you found a better way.

What is that GNARLY AF tune at the start? ⛓🎸🤘

So good! The Divided - For Tonight We're Strangers. Used with permission of course.

You say JavaScript funny

um, I think you mean I say it the correct way! eh?
