Not entirely sure what you want to achieve, but consider this program:
var a = 'foo';
var b = 'bar';
var c = { first : a, second : b };
console.log(JSON.stringify(c, null, 4));
A json object c is constructed using the values from variables a and b. Is this what you mean?
It really depends on what you're using it for such as looking up a recipe or an answer to a question. If you're using it for illegal purposes or looking up things that are seen as morally wrong by other people it can make the internet seem like a bad thing. But the internet wasn't created with that intended purpose so again it's just your own personal opinion.
