return res.send() good or bad style ?

[Jérémy Lal]

Hi,

Is it a good habit to do "return res.send(200)"
instead of simply "res.send(200)" ?

that question is slowly killing me :)

i guess it doesn't matter  since the router/middleware do not care about return values.

the return doesn't do anything it's just to short-circuit the
statement. the following are equivalent in that sense,
but one has less nesting:

if (err) return next(err);
res.send(200);

if (err) {
next(err);
} else {
res.send(200);
