Chad has written the majority of his code in Scratch and is ready to start thinking of test cases to make sure that his program functions properly, and when issues arise, fix them. Chad is also going to show his program to his classmate and ask for any feedback or changes he could add to make his program better. This process is known as what?
Iterative Development Process
Debugging
Pseudocode
Program Detection

To see if there are any bugs in the program/app.
To get input on the design of the program/app.
To see how a user interacts with the app/program.
Which of the following describes "event-driven programming?"
Commands run one at a time in the order that they are written.
Commands run one at a time in response to user interactions or other events.
Commands all run at the same time when the user interacts with the app.

run the program over and over, staring really hard at it
add some console.log statements to see what is going on
describe your program and the odd behavior to a friend
reduce the amount of code and see if the behavior improves
