Solution

  • Go 1.11 Release Notes (August 2018)

    WebAssembly

    Go programs can call into JavaScript using the new experimental syscall/js package.

    syscall/js was first introduced in Go1.11 (August 2018). Your output from the command go version is go1.6.2 l, an ancient (February 2016) and obsolete version.

    After downloading a binary release of Go1.11 or later suitable for your system from Go Downloads, please follow the installation instructions, including the instructions for Uninstalling Go for your current version of Go.
