Answer 1

It's called "Heredoc syntax", and it lets you specify large strings without using quotes. In this case, it looks like you're using it to put JavaScript code into a variable. Since you started the string with <<, you should be able to finish it with ORDER;, as you have — but you need to make sure that ORDER; occurs at the start of a line, with no whitespace before it.
