Print Statement Debugging
Print statement debugging is a fundamental debugging technique where developers insert print statements (e.g., console.log in JavaScript, print in Python) into their code to output variable values, execution flow, or status messages at runtime. It helps identify issues by revealing the internal state of a program without specialized tools, making it a quick and accessible way to trace errors and understand behavior. This method is often used as a first step in troubleshooting, especially in simple or time-constrained scenarios.
Developers should use print statement debugging when they need a fast, low-overhead way to inspect code behavior, such as during initial development, for small scripts, or when integrated development environment (IDE) debuggers are unavailable or too complex. It is particularly useful for logging specific values at key points, verifying control flow, and debugging in environments like command-line interfaces or embedded systems where advanced tools might not be supported. However, it can become cumbersome for large codebases or complex issues, where more systematic approaches are recommended.
