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

The "+" is for concatenation of strings and most of the examples are dealing with strings. What if you have a command you need to string across multiple lines, such as a compound "if" statement? You need a backslash at the end of each line that is to be continued. This escapes the invisible next line character so that it will not delimit the command in mid statement.
