How to create Arrays and Loop them such as "FOR" in logstash config file

Elastic Stack Logstash
1

I am new to ELK and need help to understand and execute the code.

I need to create two arrays
Array1-->Errcode {E00,E001,E002}
Array2-->ErrorShortDesc {a1,a2,a3,a4,a5,a6,a7}
now based to the above array values i need to find actual Error-description based on the permutation combination.

For(int i,Errcode[i],i++)
{
For(int j,ErrorShortDesc[j],j++)
{
set of Ifs to find exact error description
}
}

How can we achieve this in Logstash file
have used grok to do the pattern matching to get ErrorCode and ErrorshortDescription but now need to array it.
Currently having a big if else ladder.

Could you make use of the translate filter instead of using the big else if ladder?
