trailing commas
Trailing commatrailing comma javascript
Trailing commas (sometimes called "final commas") can be useful when adding
new elements, parameters, or properties to JavaScript code.
If you want to add a new property, you can simply add a new line without
modifying the previously last line if that line already uses a trailing comma.
This makes version-control diffs cleaner and editing code might be less
troublesome.
