Got my first mention on the engineering blog. My proudest contributions are parallel recheck and IDE services, and indexing based global find references.

It's the third time at work where I find that another slow VSCode extension is slowing things down for a fast language extension. I will write more in detail about this later, but there is the quick test results with an intentionally slow extension:

To have actual good DX, Rust probably needs to be forked to have GC and make the common case of sharing structs better, but I couldn't stop imagine a much better world where we have **fearless** concurrent mode + auto memo.
e.g. normal props and ref props need to be separate, so mutating props (maybe even access ref in render) will be impossible.
What will React look like if it's in Rust? A lot of APIs will be different and heavily bend by the borrow checker, but at the same time an entire class of react-rule violations will be impossible by construction.
