Description

Array access with optional chaining is not recognized as a value in objects. Optional chaining with array outside of an object works, but when used directly inside an object as a value, the next key isn't highlighted. If it is the first key-value pair of the object, both the key following it and its own key would not be highlighted

Steps to Reproduce

1. Open a javascript file
2. Write a key-value pair with a value using array optional chaining
3. Add another key-value pair before and after the key-value pair with array optional chaining
4. Delete the key-value pair before the one with array optional chaining

Expected behavior:

The keys of the object should be highlighted in both step 3 and 4

Actual behavior:

The key after the one with array optional chaining isn't highlighted in step 3
Both the key after and the key of the one with array optional chaining aren't highlighted in step 4

Reproduces how often:

Always

Versions

Atom: 1.53.0
OS: macOS Catalina Version 0.15.6 (19G73)

All optional chaining variants aren't supported unfortunately - issue #640 is similar
veitbajarsch in that forum suggested to install language-babel to fix the problem

Thanks for the suggestion. I've installed it, restarted atom, and tried it in safe mode. Unfortunately, the error is still there. Is there a certain setting that I need to change in language-babel after installation?

[icecream17]

I don't know, I haven't tried it, however I found gandm/language-babel#510, maybe that could help?

Thanks. Closing this because it seems to be a similar issue.
