Fast execution
From 2 comments
- How come this is so fast? I feel like the processing faster than I would get on an native compiled and run program. Are there any benchmarks?
  orsenthil on HN
- Speculation here, but I think WASM lends itself very well to JIT compilation, and V8 has one of the best compiler teams in the world.

Output box too small to view results
From 1 comment
- Having a bigger / resizeable output box would help too - running the Fibonacci example, all I can see is "0" unless I manage to find the tiny box with its invisible boundary to…

Add line numbers to source view
From 1 comment
- Nice, maybe add some line numbers to the source view. Makes dealing with compile errors a bit easier.

Which GC does goscript use
From 2 comments
- What GC is used in goscript? The upstream one, a Rust GC<> one, maybe the mini one from TinyGo, or something else custom?
  mappu on HN
- I poked around earlier and found this file: https://github.com/oxfeeefeee/goscript/blob/master/vm/src/gc.rs Perhaps someone can shed more light on how exactly it works

yaegi REPL
From 1 comment
- There's an REPL called yaegi, but it's pretty primitive (no autocompletion etc.. when I tried). There seems to be another interpreter that seems to be able to provide some…

TinyGo
From 2 comments
- I wonder how tinygo works for wasm. I’m not sure how much of the bloat is runtime (which I assume is smallish) vs how much of the standard library is just included by default.
  todd3834 on HN
- Tinygo produces very small binaries (kb rather than mb), through using the LLVM tool chain (which does tree shaking), and only (presently) supporting a subset of the standard…
