How safe is TypeScript's type safety? How much can you trust your statically typed code? Can you even consider TypeScript's type system "strong"? In this talk, we look at situations where TypeScript fails badly and learn why things have to be that way. We talk about trade-offs, workarounds, and ultimately solutions for all the damn, terrible lies we tell ourselves when using TypeScript.

JavaScript Should Come With Batteries

Luca Casonato

View at original site

Setting up JavaScript projects is no fun. Getting started involves installing and configuring node, tsc, prettier, eslint, a testing framework, a database driver, and more. Why is JavaScript not batteries included? In this talk, we'll talk about how Deno fixes this, letting you focus on building stuff. We explore what benefits full tooling integration unlocks and remember how fun it is to program if your tools help you rather than requiring your babysitting.

James M Snell

Non-browser JavaScript runtimes are growing, expanding, and evolving. At one time, Node.js was the only option. Today, we also have Deno, Bun, Cloudflare Workers, and more. How are these runtimes different? How are they similar? And how can a developer target all them?
