Having functions in Script Includes

1. Create another new Script Include, available at System Definition > Script Includes:
   • Name: square
   • Script:

function square (x) { 
  return x * x; 
} 

Notice how square is written with an initial lowercase letter, since it is a single function. SimpleMath started with an upper case letter, since it is a class.

2. You can then run this in Background Scripts in the x_hotel scope very easily:

gs.info(x_hotel.square(10)); 

It is much better to group similar functions together in a single utility class. This will also give them a namespace, which means it is less likely there will be collisions or variables with the same name.
