@ekwoka This problem is caused in your commit, please fix that

There is nothing to fix there as it is valid code.

If you are running this in/want to support runtimes that do not support optional chaining, you can setup your bundler to target older specs. Optional chaining is a transpilable feature, so setting your bundler to target es2017 or es2018 will transpile this to a collection of ternaries.

There is little reason for any modern library to not use modern js features when they are transpilable back to the oldest supported target.

If you are using CDN, you can use a cdn that allows target options like esm.sh, or chime in your support for #3625 which targets 2017 for the cdn prebundles.
