assignment. You are encouraged to post and respond early in the week to share
experiences that you are having, and to help others with theirs. This is how
coders solve tough issues: they rely on one another!
Dynamic
images and events can make a Web page pop. For some, creating this interactivity
is a snap; for others it can be a bit of a challenge.

Unit 03 Discussion
DQ1 Events,
Dynamic Images, and Modularization
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. In particular, focus on at least two of the following points while
providing sample code (with comments) of each
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.

Scholarly Resources: Scholarly resources are written with a focus on a specific subject discipline and usually written by an expert in the same subject field. Scholarly resources are written for an academic audience.
Examples of Scholarly Resources include: Academic journals, books written by experts in a field, and formally published encyclopedias and dictionaries.
Peer-Reviewed Journals: Peer-reviewed journals are evaluated prior to publication by experts in the journal’s subject discipline. This process ensures that the articles published within the journal are academically rigorous and meet the required expectations of an article in that subject discipline.
Empirical Journal Article: This type of scholarly resource is a subset of scholarly articles that reports the original finding of an observational or experimental research study. Common aspects found within an empirical article include: literature review, methodology, results, and discussion.
Adapted from “Evaluating Resources: Defining Scholarly Resources,” located in Research Guides in the GCU Library.
☐ The writer is clearly in command of standard, written, academic English. Utilize writing resources such as Grammarly, LopesWrite report, and ThinkingStorm to check your writing.
