The reasoning given by Dmitry makes perfect sense. And to my eyes:
{
/* element 1 */
},
{
/* element 2 */
},
actually looks better than:
> {
/* element 1 */
}, {
/* element 2 */
},
So if first one is not enforced in order to minimize almost empty lines
- then I will try to be using the latter in the future. (In such cases
where element consists of more than one value).
Thanks for this little lesson =)
