The top level files should indeed be removed, leaving just the two
directories
- esm stands for "es6 modules" which are the future format, very cool,
though as far as i know is not supported anywhere without some explicit
experimental flag.
- umd stands for "universal modules" and works everywhere

Bug#926871: Uncaught SyntaxError: Unexpected token export

[Enrico Zini]

Package: libjs-popper.js
Version: 1.14.6+ds2-1
Severity: important

Hello,

these toplevel scripts:

/usr/share/javascript/popper.js/popper.js
/usr/share/javascript/popper.js/popper.min.js

contain an export definition that doesn't seem to be standard
JavaScript:

$ tail /usr/share/javascript/popper.js/popper.js
…
export default Popper;

and indeed, using them in a browser raises an exception:

Uncaught SyntaxError: Unexpected token export

Using the umd/ versions work:

/usr/share/javascript/popper.js/umd/popper.js
/usr/share/javascript/popper.js/umd/popper.min.js

I find this to be surprising behaviour, as I'd expect the toplevel
versions to be valid JavaScript, and other fancy things to be in
subdirectories, but I'm happy to stand corrected.


Enrico
