Unexpected token while running node example

Start with the node.js compilation instructions in the linked documentation and the generated nodejs_demo.js named in the report. Reproduce the node nodejs_demo.js command and inspect the generated import statement against the reported syntax error; done means the documented example runs without the unexpected-token failure.

Hello,
I try to run the nodejs example found here https://www.transcrypt.org/docs/html/installation_use.html
2.5. Compiling for node.js
And get unexpected token error on node nodejs_demo.js command:
