Getting undefined in the array of strings

Question

I have the following Javascript code:-

    const mainFunction = async (message) => {
      const templateData = {};
      templateData.name = message.firstName;
      templateData.email = message.emailAddress;  
      templateData.account = message.accountType;
      console.log("message::::", message);
      const userId = message.userId;
    
      const emailAddresses = [`${message.emailAddress}`];
      console.log("emailAddresses->", emailAddresses);
}

Logs:-

    "firstName": "tom",
    "lastName": "dick",
    "accountType": "BASIC"
}

The problem is the constant emailAddress is coming as undefined but the value of the emailAddress attribute is present in the object message. I want to pass the dynamic value to this array of Strings but not working at all.

Please let me know why it is coming as undefined. Thanks

Possible cause: [Is Chrome’s JavaScript console lazy about evaluating objects?](https://stackoverflow.com/q/4057440/4642212). Try logging `JSON.stringify(message)` instead. — Sebastian Simon, Mar 10 '22 at 12:51
Why did you use the value of email address like `[`${message.emailAddress}`]` — Tushar Gupta, Mar 10 '22 at 12:53
And: why is that function `async`? You don't `await` anything. — Andy, Mar 10 '22 at 12:56
@Andy, it is not a complete function. I'm using await in the preceding statements — vinod827, Mar 10 '22 at 12:59
@Tushar, I'm trying to populate the value of an array of strings dynamically here hence used this syntax — vinod827, Mar 10 '22 at 13:00
