Final answer:
Commands inside an onEvent function run in response to specific user interactions or events, while commands outside an onEvent are executed immediately when the program starts, following a top-down execution flow.
Step-by-step explanation:
When considering how commands inside an onEvent function differ from commands outside of it, it's important to understand the concept of event-driven programming. In event-driven programming, commands inside an onEvent function are executed only when a specific event occurs, such as a user clicking a button or moving the mouse. These commands are part of the event handler and are triggered by the event.
On the contrary, commands that are located outside of an onEvent handler are typically executed immediately when the program starts, assuming they are not part of any function definition. These commands follow a top-down execution flow where each line of code is run in the order it appears in the script. This sequence of execution is generally known as the main flow of the program.
In summary, the primary difference is that the event-driven commands within an onEvent are conditional and only run in response to user interactions or other events, while commands outside an onEvent are executed as part of the program's initial run sequence.
