I have decided to create JavaScript application and run it under Node.js.
I have noticed, import and export keywords don't work. I would like to use pure JavaScript without transpilation.
Should I install some module to Node.js?
Application error:
import { spawn, Thread, Worker } from 'threads';
^^^^^^

To use ES Modules, add "type": "module" property to package.json file.
Example package.json file:
{
"name": "application-name",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"type": "module",
"dependencies": {
"threads": "^1.7.0"
}
}
