// panic: syscall/js: call of Value.Get on string
// which is coming from here: https://github.com/golang/go/blob/release-branch.go1.13/src/syscall/js/js.go#L252
// But I'm not sure how import "fmt" results in this.
// To reproduce, install Go 1.13.x and change the build tag above
// to go1.13 and run this test.
