Tinygo made a lot of progress over the years -- e.g. they've recently introduced macOS support!<p>It does indeed produce much smaller binaries, including for macOS.<p><pre><code> yuriy@MacBookAir ~/t/tinygo> time tinygo build -o test-tiny main.go ________________________________________________________ Executed in 1.06 secs fish external usr time 1.18 secs 0.31 millis 1.18 secs sys time 0.18 secs 1.50 millis 0.18 secs yuriy@MacBookAir ~/t/tinygo> time go build -o test-normal main.go ________________________________________________________ Executed in 75.79 millis fish external usr time 64.06 millis 0.41 millis 63.64 millis sys time 96.76 millis 1.75 millis 95.01 millis yuriy@MacBookAir ~/t/tinygo> ll total 5096 -rw-r--r--@ 1 yuriy staff 74B 3 Apr 19:17 main.go -rwxr-xr-x@ 1 yuriy staff 2.3M 3 Apr 19:18 test-normal* -rwxr-xr-x@ 1 yuriy staff 192K 3 Apr 19:18 test-tiny* yuriy@MacBookAir ~/t/tinygo> cat main.go package main import "fmt" func main() { fmt.Printf("Hello world!\n") }</code></pre>

Writing embedded code with an async-aware programming language is wonderful (see Rust's embassy), but wonder how competitive this is when you need to push large quantities of data through a micro controller, I presume this is not suitable for real-time stuff?
