tags: "<tag1>, <tag2>, <tag3>, ... ",
typeKeywords: "<typeKeyword1>, <typeKeyword2>, <typeKeyword3>, ... "
},
jobParams: {
outputLayerName: "{\"serviceProperties\":{\"name\":\"Name of the output feature service\"},\"itemProperties\":{\"itemId\":\"<itemId>\"}}",
...
}

context: '{"outSR":{"wkid":102100}}',
isProcessInfo: true,
returnFeatureCollection: true
}).then(function(result){
console.log(result);
});
//the "result" argument above:
//{
// "cost": 1.472,
// "totalRecords": 1472,
