• Version: v8.0.0 (although announcement claimed to remove the ' v' )
• Platform: Linux 4.4.0-77-generic Updated README with less node.js-centric content, and more Node Forward. #98-Ubuntu SMP Wed Apr 26 08:34:02 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
• Subsystem: Likely Error

Steps to reproduce

let foo = 'bar';
throw `${foo}baz`;

Expected result

Exception thrown with message barbaz.

Actual result

Exception thrown with message ${foo}baz.

This does not happen on Firefox.

Hmm, strange, it works for me in the repl:

> let foo = 'bar';
undefined
> throw `${foo}baz`;
barbaz

I can't reproduce on macOS with 8.0.0 or master.

$ node test.js 

/Users/cjihrig/iojs/node/test.js:2
throw `${foo}baz`;
^
barbaz

@Ryuno-Ki Can you provide the full literal output with the thrown error?

[jasnell]

Also unable to reproduce.

@Ryuno-Ki Are you using source code processors / transpilers like babel?

[Ryuno-Ki]

Ah, maybe it is not a bug, but a feature …

$ cat test.js
let foo = "bar"
throw `${foo}baz`
$ node test.js 
$HOME/Projects/$REPO/test.js:2
throw `${foo}baz`
^
barbaz

But after adding an npm script for it and running that, I get

$ npm run throwaway
> $REPO@$VERSION throwaway $HOME/Projects/$REPO
> node ./test.js


$HOME/Projects/$REPO/test.js:2
throw `${foo}baz`
^
barbaz
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! $REPO@$VERSION throwaway: `node ./test.js`
npm ERR! Exit status 1

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

So it could be, that it outputted me a raw view of the file's content … In that case, sorry for the noise :)

@Ryuno-Ki thank you for the clarification and follow up.
