javascript - JSON.stringify doesn't escape?

I'm using `JSON.stringify? to stringify an object, but the quotes are not escaped? Am I misunderstanding that it's suppose to escape the quotes?

This is outputted into the template without any of the quotes being escaped:

{"console":{"free":false}}

stringify the object twice does the trick

console.log(JSON.stringify(JSON.stringify({"console":{"free":false}})));
// "{"console":{"free":false}}"
