   Go 1.11 adds an experimental port to WebAssembly (<code>js/wasm</code>).
 </p>
+<p>
+  Go programs currently compile to one WebAssembly module that
+  includes the Go runtime for goroutine scheduling, garbage
+  collection, maps, etc.
+  As a result, the resulting size is at minimum around
+  2 MB, or 500 KB compressed. Go programs can call into JavaScript
+  using the new experimental
+  <a href="/pkg/syscall/js/"><code>syscall/js</code></a> package.
+  Binary size and interop with other languages has not yet been a
+  priority but may be addressed in future releases.

   "<code>js</code>" and <code>GOARCH</code> value "<code>wasm</code>",
