Final Answer:
To start a debug session in VS Code, first, open your project and set breakpoints in the code by clicking on the gutter next to the line number. Then, press
or go to the Debug menu and select "Start Debugging" to initiate the debug session.
Step-by-step explanation:
To commence a debug session in VS Code, the initial step involves accessing your project within the editor. Once the project is open, the next crucial action is setting breakpoints in the code. These breakpoints are markers that signify where the execution of the program should pause for inspection. They can be set by clicking on the gutter, the vertical bar beside the line number, at the desired location in the codebase.
Upon placing breakpoints, the process continues by initiating the debug session itself. This is accomplished by pressing the `F5` key on the keyboard, triggering the "Start Debugging" function within VS Code. Alternatively, one can navigate to the Debug menu located in the top panel of the editor and select "Start Debugging" from the available options.
Activating the debug session halts the program's execution at the specified breakpoints, allowing for meticulous examination of the code's behavior, variables' states, and various other debugging features. This method aids in identifying and rectifying errors, streamlining the development process by providing a comprehensive insight into the program's execution flow.
