The debugging experience was primarily what pushed me to switch.

After working in NodeJS for the better part of a decade there were still
new issues cropping up regularly in mature codebases - with the Rust
rewrite most of the issues I faced in Node (and wrote test suites
extensively for) have been resolved through the type system.

It's just not possible to write most bugs I would normally write in non
ML-languages because every valid application state is modelled by sum-type
algebraic data structures (ie. Rust Enums).

An invalid application state would be a compiler error, same for race
conditions, use after free, null pointers, and immutability. Even SQL
statements are type checked at compile time against my database tables
thanks to sqlx <https://github.com/jmoiron/sqlx>. The only meaningful
problems I deal with now are deadlocks.

Performance is also looking dramatically better and memory usage is down -
those might have been possible with optimization in NodeJS but then my code
would have been more difficult to maintain. I just got them out of the box
with Rust in addition to the maintainability improvements.
