Data Flow Analysis
Data flow analysis can show us potential errors in our code logic.
Data Flow Analysis is a powerful tool that shows you how data moves through your code. It can locate places where we could have errors in our code. For example, if we use a negative number for initialising an array, or checking for negative values where the value couldn't be negative. Use Code | Analyze Code | Data Flow to Here or Code | Analyze Code | Data Flow from Here to analyze upstream or downstream data flow**.
