Congratulations, you’re a software developer!

It doesn’t matter if you’re a hero-worshipped architect at Amazon who sits on Twitter all day, or a new developer just starting to build your first apps. Everyone deals with the same issues, no matter where you’re at in your journey.

So what’s the solution? Giving us money, obviously.

Welcome to ui.dev – everything you need to succeed as a modern JavaScript developer.

Courses

We're obsessed with making the most effective developer courses on the planet. On average, it takes us around 1,500 hours to create a new course. While others prioritize quantity, we optimize for quality.

Each course follows the same proven format.

  • Non-Contextual Introduction

    The first time you're introduced to a topic, any extra contextual information you have to process only serves as a distraction. Although it takes more time, our non-contextual introduction comes in two forms, video and text. This way, no matter how you prefer to learn, there's an option for you.

  • Quiz

    Nothing fancy here. After learning about the topic you'll receive a quiz to make sure you have a solid conceptual understanding before moving on to the hands-on practice.

  • Non-Contextual Practice

    Similar to the non-contextual analysis, context is everything. The first time you're hands-on with a new topic, any extra contextual information you have to process only serves as a distraction. This is why we first have you work through small, focused practice problems before you ever see the new topic in the context of a larger project.

  • Contextual Practice

    You've probably experienced it before, you feel like you're learning so much going through a tutorial only to hit a wall once it's time to actually apply that knowledge outside of the context of the tutorial. All the non-contextual practice in the world is useless if you're not then able to take that knoweldge and apply it towards a (contextual) production level codebase.

Events

How would you like to spend 60 minutes learning CSS from Josh Comeau?

Want to pick the brain of D3 expert Amelia Wattenberger?

How about a simple intro to React Query from its creator Tanner Linsley?

We often bring in experts from the JavaScript ecosystem to give conference-style talks and trainings around the hottest topics in web development - and you're invited.

You'll get access to our full catalog allowing you to binge watch a bunch in a row while you’re “working” from home.

Core Beliefs

  • We believe that growth is hard

    We’re not here to sell you a magic pill that will turn you into a 10x-unicorn-developer-ninja-engineer. True learning takes consistent work and deliberate practice. It’s not easy, but it’s attainable when you have a solid plan, proven curriculum, opportunities to practice, built-in accountability, and a network of like-minded developers working alongside you.

  • We believe in shipping

    Building is the most effective way to learn quickly. Even when it’s not perfect, shipping consistently helps you stack up small wins over time that compound your abilities. It can be scary to release new things, but we create a safe place for you to do so.

  • We believe in empathy

    Being able to understand and share the feelings of others will help you be a better developer, builder, and person. Empathy is a force multiplier on every skill you have and the best way to develop empathy is by building relationships with people who look, think, talk, and act differently than you.

    This was good course, it covered some things about JS that I didn't really understand or know. It's worth spending the time going through.

    Fantastic course! Frequently humorous but never dumbed down, with quiz questions that actually make you think and challenge your understanding of the content. Tyler has a unique ability to explain the foundational principles behind commonly used patterns, resulting in many celebratory Aha! moments along the way.

    I super love the course. Quickly got me up to date with Typescript. Although I've been coding Typescript for a while, I only felt I got the fundamentals down after this course. Highly recommend.

    Great course! The way information is presented is very clear and easy to follow. Video+text transcript is perfect. If this course would be updated with EC2022, I would take it again :)
