Yes.  With a trailing + it is immediately obvious to a human reader of
the line, without looking ahead, that there is a continuation.  That
applies particularly in the case of a single continuing line; with many
continuing lines, the overall structure will be noticed peripherally
while the first line is being considered - if they are on-screen.

JavaScript treats them the same, although there may be a very small
browser-dependent speed difference at the parsing stage.  Obviously you
can measure that well enough to see whether it is significant.
