Setting msg.increment = 0, increments by 1

[karwosts]

If msg.increment is set to 0, the node increments by 1. I would have expected it will keep the same value.

If it is set to "0", the node increments by 0.

var increment = Number(msg.increment || 1);

0 || 1 evaluates to 1.

The same problem if msg.reset = 0, it will just ignore it. I actually haven't found any way to reset the counter to zero.

That seems both true. I still need to look at it, sorry. For reset to it's Initial value you can use msg.reset = true;.

0 ?? 1 would evaluate to 0
var increment = Number(msg.increment ?? 1);
