There are several ways that you could create a common reusable shared function in Karate Test Automation but I method I prefer is to write it in Java and then call it from the feature file.

Define the function in feature file background section and you will be able to call it like a normal function. See screenshot below.
When the scenario is ran, it will print the random numbers declared in the Java file.
