var stream = json_array_writable_stream()
stream.write(1)
stream.write("string")
stream.write(null)
stream.write({a:"Aa"})
stream.write(void(0)) // Will ignore undefined by default
stream.end()

var stream = json_array_writable_stream(
{
    spaces: 0,

    replacer: function(key, val) { return (key == "key1") ? "Replacement value." : val },
    separator: ",\n",
    replace_undefined_by: null // In case you want these keys to show up in your JSON.
