Question:
The ability to animate graphics with JavaScript has resulted in increased interactivity of Web sites. As we add more functionality into our scripts, it is important that we take the time to modularize our code to make it more efficient. We want to ensure our functions are split up for reuse.
Research and describe some tips and suggestions for someone new to JavaScript to get started:
- Explain which events and methods we can use to handle user interaction with images.
- Distinguish among HTML events, mouse events, and keyboard events.
- Describe the use of cross-browser compatible functions or methods for attaching and detaching event handlers.
- Describe the use of images and preloaded images in applications like image rollovers and slide shows.
- Describe setTimeout, setInterval, clearTimeout, and clearInterval.
- Explain why modularizing a program makes it more efficient.
- Identify the advantages and disadvantages of modularization.
