(module (import "console" "log" (func $log (param i32))) (func $main ;; load two values onto the stack i32.const 10 i32.const 20 ;; drop the top item from the stack (`20`) drop call $log ;; log the top value on the stack (`10`) ) (start $main) ) const url = "{%wasm-url%}"; await WebAssembly.instantiateStreaming(fetch(url), { console }); Syntax
