One of the functions in the flask.json module is jsonify(). It converts data to JSON format and encapsulates it in a Response object with the application/JSON mime-type. It's worth noting that jsonify is occasionally imported directly from the flask module rather than the flask itself. In other words, jsonify() is a Flask assist method for appropriately returning JSON data. jsonify() provides a Response object with the application/JSON mime-type set, whereas json.dumps() only returns a JSON data string. This could have unforeseen consequences.
