Line continuation characters in JavaScript

Question

What is the best practice for line continuation in JavaScript? I know that you can use \\ for strings. But how would you split the following code?

Answer 1

If I properly understood your question:

var statement = con.createStatement('select * from t where '
                                  + '(t.a1 = 0 and t.a2 >=-1) '
                                  + 'order by a3 desc limit 1');

For readability, it is fine to align + operator on each row: Anyway, unless you're using Ecmascript 2015, avoid to split a multiline string with \, because:

1. It's not standard JavaScript
2. A whitespace after that character could generate a parsing error
