Just assign the object you need stringifying to a variable and pass that to JSON.stringify():

<script>
   var myNewObject = {key1:true, key2:17, key3: [
    {k1: 10, k2:true, k3: "test" },
    {k1: 11, k2:true, k3: "testing" },
    {k1: false, k2:42, k3: "foo" },
    ]}; 

    var stringifiedObject = JSON.stringify(myNewObject);
    console.log(stringifiedObject);     
</script>
