## Definition

a computer program that helps you find and fix mistakes in your code. It lets you stop the program at any moment to see what is happening inside.

For teachers: a software tool used to test and identify errors in other computer programs. It allows for the inspection of variables and the execution of code line by line to isolate logic or syntax faults.

## Examples

- I used a debugger to find the error in my script.
- After the application crashed, the developer launched the debugger to see which line of code caused the memory leak.
- While print statements can provide basic insights, a professional debugger offers a more granular view of the program's state, enabling the developer to step through complex recursive functions.

## Usage notes

- Commonly used in technical and programming contexts; often paired with the verb 'run' or 'launch'.
