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. If you are new to JavaScript, or want to just get comfortable with the fundamentals, I'd recommend you take myBeginnerJavaScript.com course - use the codeJAVASCRIPT30 for an extra $10 off.

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 inconsole.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 mypremium courses. It all works out!

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

I answer everything over atwesbos.com/uses. Feel free totweet me any more questions!

I have a question, can I email you?

While I'd absolutely love to help everyone out, there are 737,716 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 intoyour account, or create an account with the same email you used to get the series.

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.

I found a typo or errata

If it's a typo on the site, please shoot me an emailhere. 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.
