Chicago JavaScript Meetup Group

Join us in June for another in person ChicagoJS meetup!

Josh Hoeflich, Research Engineer at Northwestern University, will be talking about how to use JavaScript to automatically detect bugs in TypeScript type declarations.

If you’ve ever used a JavaScript library from a TypeScript program, you’ve probably had to install third-party type declarations. These definitions often have problems—it’s easy to make subtle typos, and if the underlying JavaScript represented by the types changes, the declarations can become inaccurate. As such, how can we check whether the types for a given library are correct? Luckily, programming language researchers developed a technology called contracts that can help us find the answer by dynamically checking JavaScript values at runtime. This talk discusses an automatic bug-finding pipeline named Scotty which was built using contracts and facilitated over 100 merged pull requests for 100 separate libraries into DefinitelyTyped.

Joe Meyer, Mobile & Application Architect at Rightpoint, will be taking a simple a React web component and converting it to a native mobile component using React Native. Then, migrating a web-only app to be cross platform (iOS, Android, and Web) using a single code base. As part of the talk, he’ll also be setting up a basic React Native project using Expo.

We're so excited to be hosted by Rightpoint.
Their offices are located at 29 N Upper Wacker Dr, Chicago, IL 60606.

⭐️ Please be sure to bring a photo ID. You will need to check in with security at the front desk.

💻 WEB COMPONENT TRAINING 💻

This training is designed to provide you with the knowledge to build reusable, modular, and encapsulated components for your web applications.

Throughout this hands on course, you'll have access to interactive examples, code snippets, and exercises to reinforce learning. By the time we wrap, you'll have built your own web component that can easily be dropped in to any frontend JavaScript framework or vanilla JavaScript app.

You'll walk away from this training with a solid foundation in web component development and the skills to create reusable components that enhance the modularity, maintainability, and reusability of your web applications.

Your trainers are Bitovi React Developers Bavin Edwards and Arthur Pankiewicz.

Bitovi offers consulting, training, strategy, and staff augmentation. If you’re looking for a collaborative, validation-driven team of experts who can help you swiftly deliver your next app, you’ve found us.
