IR command creation

General
1

I have the following function node that takes source11,a global variable, splits the numbers out, matches them to their respective IR commands for each number and then sends that on. I create a global variable called matchedCommands11. Right now my source11 global variable is set to 111; however, my matchedCommands11 global variable is set to the IR commands for 22. My function node code below is not updating the matchedCommands11 variable with the correct value in this case it should be array(0:)1 array(1:) 1 and array(2:) 1. Can anyone tell me what I'm doing wrong?

matchedCommands11 array[2]
0: "1,58000,1,37,23,351,23,164,23,164,23,164,23,94,23,164,23,94,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,351,23,164,23,164,23,164,23,94,23,164,23,94,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,164,23,351"

I suspect you are missing the fact arrays are zero based.

e.g, your array is as below (modified for readability)

var irCommands = [
    "A",
    "B",
    "C",
    "D",
    "E",
    "F",
    "G",
    "H",
    "I",
    "J"
    // Add more commands as needed
];

So when you request elements 1, 1 ,1 you get ['B', 'B', 'B']

If you were expecting ['A', 'A', 'A'] then you need to deduct 1 from the input value for a zero based index offset.

A better solution would be to use a look up object instead of an array.
And since this is node-red, a low/no-code solution might be better still
