Optimizing Javascript for fun and for profit
I often feel like javascript code in general runs much slower than it could, simply because it’s not optimized properly. Here is a summary of common optimization techniques I’ve found useful. Note that the tradeoff for performance is often readability, so the question of when to go for performance versus readability is a question left to the reader. I’ll also note that talking about optimization n
A new way to bring garbage collected programming languages efficiently to WebAssembly · V8
A recent article on WebAssembly Garbage Collection (WasmGC) explains at a high level how the Garbage Collection (GC) proposal aims to better support GC languages in Wasm, which is very important given their popularity. In this article, we will get into the technical details of how GC languages such as Java, Kotlin, Dart, Python, and C# can be ported to Wasm. There are in fact two main approaches:

V8 Torque user manual · V8
V8 Torque is a language that allows developers contributing to the V8 project to express changes in the VM by focusing on the intent of their changes to the VM, rather than preoccupying themselves with unrelated implementation details. The language was designed to be simple enough to make it easy to directly translate the ECMAScript specification into an implementation in V8, but powerful enough t
