Why pick Golang when SWC has already done most of the heavy lifting?

Ah they're worried about unsafe code and delays. But.. we have AI for this grunt work and backchecking? Perplexing. https://www.reddit.com/r/javascript/comments/1j8s441/comment/mh7ms9n/

It sounds like they are doing more of a "find and replace" style rewrite rather than a from-scratch rewrite. Data structures and algorithms not really changing, etc. Which is quite interesting - my mental model is that usually the main benefit a rewrite is the chance to revisit the core DS/A decisions.

TypeScript typing system is full of JS idiosyncrasy and it branches off from some mandates found in programming type theory that is common in other widely implemented type systems. There are few people in the world who comprehend it and most of them probably work on TypeScript. Having that in mind, make sense they will keep the core intact as all the tactile knowledge gained over the years of few individuals would go to waste.

From the explanatory video, it seems they consider it more a “port” than a rewrite. Probably speeds up the process and makes it easier to convert the existing tests.
