Google script - when not to use a semi colon statement terminator

Edit Subject

Hi, Nick.

I'm going to forward your question to the author to see if I can get this answered for you.

Hi Nick, thank you for purchasing my book.

Have a look at the next line in the code:
.addCallbackElement(mainPanel);

The period at the begging tells us that this is a continuation of the statement. By putting a semicolon at the end you break the statement.

The reason you will see this in code is to make it more readable by fitting it all into one window or simply to provide some organization. JavaScript will ignore the white space between the code fragments.

Happy coding,
James

Hello James,

In my version of the book, this is what I see at the top of page 41:

button.addClickHandler(validateEmail)

//handler
var handler = app.createServerHandler('contactMe')
.validateEmail(email)
.addCallbackElement(mainPanel); button.addClickHandler(handler);

---------------------------------------------------------------------------------------------
The next statement is therefore:

var handler = app.createServerHandler('contactMe')
.validateEmail(email)
.addCallbackElement(mainPanel); button.addClickHandler(handler);

and there is no semi-colon terminator after
button.addClickHandler(validateEmail)

So in the code I tried out there was no semi-colon after:
button.addClickHandler(validateEmail)

Regards,

Nick
