Advanced use of functions
Once you understand the basics of how Analytics functions work, you're ready to learn how to use them throughout Analytics.
The tutorials in this section show you how to use functions in computed fields, embedded in commands, and in scripts. The true usefulness of functions will become apparent as you start to use them with these core Analytics features.
Don't worry if you aren't familiar with computed fields or scripts. You will be introduced to them in the course of the tutorials.
Note
Using functions in these other situations is a little more involved than the usage presented in previous tutorials. However, the functions themselves behave in exactly the same way.
Remember that you can quickly and easily test any function in the Analytics command line to see what it does: Familiarizing with different functions.
