Try these first

1. 1.

   What does an event represent in EDP?

   Hint

   Think about what happens when you interact with a program.

2. 2.

   What is the role of an event handler?

   Hint

   Consider what action occurs following an event.

3. 3.

   What does Event-Driven Programming prioritize?

   • A sequence of commands
   • User interactions
   • Static programming

   Hint

   Think about how modern applications respond to users.

4. 4.

   In EDP, what is an event handler?

   • True
   • False

   Hint

   Recall the function that runs when an event occurs.

5. 5.

   Design an application that demonstrates the principles of EDP, including event sources and handlers. Describe the roles of each component.

   Hint

   Consider how each component interacts in real-time!

6. 6.

   Evaluate a given code snippet that implements EDP. Identify potential issues, such as callback hell or performance bottlenecks.

   Hint

   Look for patterns where callbacks are deeply nested.
