What is typescript-deno-workshop?

This repository contains the course materials for a one-day workshop on TypeScript and Deno, taught by Eve Porcelxlo through the CascadiaJS conference. Rather than being a software tool you install and run, it's a structured learning curriculum with hands-on exercises and example code that walks participants through two related technologies over the course of a single day. The workshop is split into two halves. The morning covers TypeScript, which is a version of JavaScript that helps catch errors before your code runs by letting you describe what kind of data your variables and functions should expect. You start with basics like primitive types, then move to more advanced concepts like generics and classes. The afternoon shifts to Deno, which is an alternative runtime for running JavaScript and TypeScript outside the browser, think of it as a competing option to Node.js. The Deno portion covers its built-in security model, the tooling that comes packaged with it (like a code formatter and test runner), and how to use familiar web browser APIs on the server side. This material is aimed at developers who already know basic JavaScript but want to level up. The prerequisites listed are basic JavaScript knowledge, Node.js installed on your machine, and a code editor like Visual Studio Code. Someone might work through these materials if they're preparing to use TypeScript at a new job, or if they're curious about Deno and want a guided introduction rather than figuring it out solo. The repository is organized into folders that match the schedule, with each session containing its own subfolders for individual topics. This makes it easy to follow along during a live workshop or work through the material self-paced. The curriculum also points to official documentation and resources for both TypeScript and Deno, so participants can continue learning beyond the workshop itself.
