Why Are They Useful?

Understanding the utility of functions is best illustrated through examples. By using functions, you can create variables to:

• Check Recent Transactions: Determine if a transaction occurred within the last 30 days.
• Identify Significant Changes: Verify if the current transaction is 200% higher than the average of past transactions.
• Sanction List Matching: Check if the sender's name closely matches a name on a sanctions list.
• Detect Abnormal Activity: Identify if the number of transactions has increased abnormally.
