什么是JSON/JavaScript的日期文字(如果存在这样的东西？)

我正在使用带有Node.JS的EJS,并将JSON对象传递给它,但需要将其作为页面中的可用对象进行访问.我从这里得到了意外的令牌o错误:

var initData=JSON.parse(<%-JSON.stringify(list)%>);

我不知道这里有什么不对.

这是渲染时文件中的样子:

var initData=JSON.parse([{"title":"South Hills Health System - University Health Center","adr":"200 Lothrop St,15213","coords":"40.441875,-79.960813","images":[],"tags":[],"_id":"51c0e9798384f40000000017"},{"title":"Bombay Food Market","adr":"4605 Centre Avenue, Pittsburgh, PA 15213, USA","coords":null,"images":[],"tags":["indian","groceries","ethnic","store"],"_id":"51c0519e02b7cbec73000002"}]);

我怎么能够:

1. 将带有标志的JavaScript RegExp转换为String文字(想想JSON),
2. 并将该文字转换回正则表达式？

例如使用String "the weather is nice today":

var myRe = new RegExp("weather","gi");
var myReToString = myRe.toString(); // myReToString is now "/weather/gi"

var myReCopy = /* How to get this copy only from myReToString ? */

要修改原始的RegExp属性,请参阅torazaburo的答案.
