No support for optional chaining

[pmrotule]

Currently no support for optional chaining: https://babeljs.io/docs/en/babel-plugin-proposal-optional-chaining

Since it is now possible to use it with Babel, it would be great to be able to use it in Vue component.

Hi @pmrotule. Actually this issue has no relation to language-vue , since the support for optional chaining your need should be provided by the javascript language package you used. Give any package providing source.js.jsx grammar (like this) a try!

@aidistan I'm using the core package language-javascript which fully support optional chaining and indeed, I don't have any highlighting issue in normal javascript files. Moreover, the javascript itself within the script tag of the Vue single-file component has no highlighting issue or syntax error, it only breaks from the closing tag </script>. This must be an issue coming from language-vue.

@pmrotule You're right. It's comfirmed. I'm quite occupied in these days. Will look into it ASAP.

@aidistan After looking into it a bit deeper, I realized that the problem is not coming from this package, but from embedded script. I mentioned that it was fully supported by language-javascript, but it actually only works properly in javascript files and not within a <script> tag in HTML.

language-vue use source.js.embedded.html and therefore has the same issue as any other html files. I reported it to language-javascript. Sorry about the confusion.
