What did you do?

1. Download wasm_exec.html and wasm_exec.js

$ curl -sO https://raw.githubusercontent.com/golang/go/master/misc/wasm/wasm_exec.html
$ curl -sO https://raw.githubusercontent.com/golang/go/master/misc/wasm/wasm_exec.js

2. Create a wasm file that print string to console
   e.g. main.go

package main
import "fmt"
func main() {
        fmt.Println("Hello, go/WASM!")
}

$ GOOS=js GOARCH=wasm go build -o test.wasm main.go

3. Serve the files
   e.g. server.go

package main
import "net/http"
func main() {
        http.ListenAndServe(":8000", http.FileServer(http.Dir(".")))
}

$ go run server.go

4. Go to the URL in the browser
   (tried Chrome 70.0.3538.102 (Official Build) (64-bit))
   (tried Chrome 72.0.3618.0 (Official Build) canary (64-bit)
   e.g.

http://localhost:8000/wasm_exec.html

What did you expect to see?

e.g.

$ go version
go version go1.11.2 darwin/amd64

$ curl -sO https://raw.githubusercontent.com/golang/go/master/misc/wasm/wasm_exec.html
$ curl -sO https://raw.githubusercontent.com/golang/go/master/misc/wasm/wasm_exec.js

Are you using Go 1.11.2 but with wasm_exec.{html,js} at tip? Mixing them doesn't work. You'll need to use the same version of Go and wasm_exec.{html,js}.

The same issue I found

@cherrymui I see. Thank you for the reply.
In that case, issue can be closed.

@anymost Like me, you probably mixed 1.11.2 with master's wasm_exec.{html,js}.
Instead, use https://raw.githubusercontent.com/golang/go/release-branch.go1.11/misc/wasm/wasm_exec.js
or compile Go binary from source at master.

[anymost]

@gin thanks, I'll try
