Let's code together - bringing F# to JS world.

Javascript has conquered the software development world - developers can use it in the browser, on the server, to write mobile apps, on the desktop with Electron, and even to create serverless services. Whether you like the language or not, the truth is JS developers have built an incredible ecosystem with libraries and tools to do almost anything. During the talk, I'll show how to bring the power of F# - robust, static type system with type inference, pattern matching, and immutable design, and succinct syntax - to this vast and rich JS world using Fable - F# to JS compiler. It will be a practical talk, showing various use cases of Fable - from building React-based web applications, through building serverless, edge web services using Cloudflare Workers, creating mobile apps, to building VSCode extensions.
