I signed it!

CLAs look good, thanks!

Nicee, thank you for the PR!

We're currently working on #382, and the feature will add the properties() method that would return object handles.

Given this, let's scope this PR only to the attribute() method.

@aslushnikov very well. I removed the property method.

@batiste please run the npm run doc command to update table-of-contents in api.md and satisfy documentation linter.

@aslushnikov done!
