Fails to compile .js file to es5? -- set plugin include

[yavorski]

What happens and why it is wrong

I have a project with mixed .js, .mjs and .ts files which all should compile down to es5.
What is going wrong is that the plugin is compiling only files with the .ts extensions.
Is it possible to compile the .js files too?
I already set "allowJs": true in tsconfig.json.

Here is a test repository reproducing the issue ->
https://github.com/yavorski/rollup-typescript-fail-js.

As you can see in the compiled file async/await is not compiled...

Any advance would be helpfull.

As I said, any advice would be helpful.
Thanks in advance!

@yavorski Check out include option, by default it is only processing ts and tsx: [ "*.ts+(|x)", "**/*.ts+(|x)" ]

typescript({ include: [ "*.ts+(|x)", "**/*.ts+(|x)", "*.js", "*.mjs" ] })
