If you write JS or TS, probably every tool you use daily is currently being rewritten in Rust.

This has advantages (have you heard that Rust is "blazing fast"?), but also potential downsides.

The evolution of JS from the dark days before async/await was fuelled by tooling written in JS. If our tools migrate to a language we don't know, will we lose the ability to control or customize them?

In this talk, I'll explain how in Oxc (the compiler underlying the next generation of the open source Vite bundler), we're trying to "square the circle" - providing rich customisation via plugins written in JS, but maintaining the exceptional performance of Rust - and take you into the nerdy details of memory layouts, allocators, garbage collection, and the tricks that make it possible to have our Rusty cake and eat it with a JS fork.

In the ever-evolving landscape of web development, bundlers play a crucial role in optimizing application performance. Rspack, a Rust-based bundler, has emerged as a promising alternative to traditional tools. This presentation will delve into the intricacies of Rspack, exploring its architecture, key features, and performance advantages. By the end, you will have a solid understanding of how to harness Rspack's power to create high-performance web applications.

Bitwise operators are often overlooked in the JavaScript ecosystem—viewed as obscure or only relevant in low-level programming. However, they are among the most powerful and efficient tools available right in the browser. Because they operate directly at the number level, bitwise operations are incredibly fast in JavaScript engines, making them ideal for a wide range of practical uses:

Collision masks in browser-based game engines

Interfacing with WebAssembly

Lightweight compression techniques

Real-time audio/video streaming

Clever hacks for text encoding and emoji maths
