// Given a JSON message like:

    JSON.stringify(
        {
            "name": "David",
            "age": 22
        }
    )
);

// Check whether a node is a numeric value
if (message.isJSONNumber("/age")) {

}

if (!message.isJSONNumber("/name")) {
    // The name node is a string, not a number.
}
