为什么json编码从php发送数据到javascript（Laravel）？

Question

I have just read this question and noticed a lot of the answers showing json encoding. I'm just wondering why? Is it for some kind of security? So for instance in Laravel would this be the correct way to pull stuff in

var date = '{!! json_encode($event->date) !!}',
parseDate = JSON.parse(date);

//use parseDate here.

Sorry for making a whole new question, but I don't have the rep to comment on the original question :/

Generally, JSON is used to send data from the server to the browser when you want to retain it's structure. It is easy to parse in Javascript with the result being an array that matches the original array in the server language (like PHP). For simple, single values, it isn't really needed.
