Ashley is a JavaScript Infrastructure developer at Bloomberg and a TypeScript contributor. As a TC39 delegate, he has helped advance several JavaScript language proposals, notably championing ES2023’s Change Array by Copy.

Unlike Porffor, most JavaScript engines cannot execute TypeScript natively and therefore need to compile TypeScript into JavaScript before it can be run. This talk will explore an innovative compilation technique for TypeScript that can be used to speed up this type-stripping process, in addition to offering developers several other benefits.

Oliver is a TC39 Invited Expert and the creator of Porffor – an experimental Ahead-Of-Time (AOT) JavaScript engine that can compile TypeScript to Wasm and native code. It has graduated from being a hobby project to now being a full-time activity.

In this talk, Oliver will show how native TypeScript support in JavaScript engines can present interesting optimization opportunities. Type annotations from TypeScript can act as hints to the AOT compiler to allow optimizations that reduce output size, improve performance, and more!

This talk is going to tell the journey of the integration of TypeScript in Node.js with --experimental-strip-types Main point are: - Why waiting so long - How we revolutionized typescript support without source-maps - Shipping it - Unflagging - Next steps

We talk a lot about type safety for so many applications. Little attention is given to search -- ask a developer and one of the most ubiquitous features implemented is search. How can we make this better?

If you’ve asked or wondered how to make the search experiences you build add to web applications better in function, speed and accuracy then this talk is for you! We’ll dive a little deeper into search, tackling how Typescript helps out with an engaging demo to top it off.
