I have a function that returns a hash, given certain parameters:
build_message = function(from, to, bcc, subject, tag, htmlbody, textbody, replyto) {
message = {"From": from,
"To": to,
"Subject": subject,
"HtmlBody": htmlbody,
"TextBody": textbody};
message.encode();
}
Some of these parameters, like bcc
and replyto
are optional. If the caller provides null values for them, they must not be present in the hash I return. That is to say, "Bcc": bcc
must only be present in the hash if the bcc
argument is non-null.
Here is my first attempt, but the parser doesn't like it (this goes right before the message.encode()
line of the function):
bcc_body = bcc => {"Bcc": bcc} | {};
message.put(bcc_body);
Is using the put()
operation allowed on a variable inside a function like this? If so, is something wrong with my syntax?
You can use .put()
inside a function, but remember that it returns a new hash and leaves the original unmodified.
Try ending your method like this:
bcc_body = bcc => {"Bcc": bcc} | {};
newmessage = message.put(bcc_body);
newmessage.encode();
