spoken like a middle manager.

why would anyone send JavaScript from the php? why care about duplicating a couple json translations and null checks... it's all code is today anyway.

and switching languages? you can't use most of js as it is. even something as simple as split() have so many weird bugs that everyone just code from a utils lib anyway.

Oh hey, insults. Those are fun.

spoken like someone who's not experienced enough to realize that duplicated code needs to be kept in sync, and then when it inevitably isn't, it'll lead to incidents, and also can't write JavaScript without using leftpad.
