Switch Node and Jsonata and/or range?

General
1

Guys,

Just looking to simplify some flows and wondering if i could use the switch node

Essentially i want to feed in a Month number (between 1 and 12) and then based on the value(s) switch to one of the outputs. So for instance i could have

Month number = 1,2,3,11,12
Month Number = 6,7,8
Month number = 4,5,9,10

If the switch matched any of out the blocks i would want them to go out a specific output - so if it saw 1 or 2 or 3 - it would send it out Output 1

4 or 5 or 10 would go out output 3 etc.

I looked at contains as an option - but that seems to be string only ?

Obviously i could do it in a function node fairly easily - just looking at ease of ongoing maintenance by using a provided node

As usual find it 5 minutes after finish looking - i think its because i am scared of JSONATA !!

Anyway - anyone else looking

You can select the switch node as a Jsonata expression and then just put in

msg.month = 1 or msg.month = 2 etc etc

Example flow below
