JSON.stringify with square brackets

I have a JS object:

var source = {};
source.quantity = 1;
source.text = 'test';

Now I JSON it:

var json = JSON.stringify(source);

json looks like this: 

{"quantity":"1","text":"test"}

I would like it to be like this:

[{"quantity":"1"},{"text":"test"}]

Ho can I do this?

Solution

  • Get all the keys as an Array them map them to Objects as key-value pairs from source

    JSON.stringify(
    Object.keys(source)
          .map(
              function (e) {
                  var o = {};
                  o[e] = source[e];
                  return o;
              }
          )
); // "[{"quantity":1},{"text":"test"}]"
