IT 3215: Unit 01 Discussion DQ1 Getting Started With JavaScript
JavaScript
has been one of the most popular scripting languages for dynamic interactivity.
It is a completely different language from HTML5 and CSS3, and it can be
challenging for those without programming experience to begin. Research and
describe some tips 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) for each:
Explain how
different browsers handle JavaScript code. What considerations must be made
when developing for different browsers?
Describe
the use of JavaScript comments, including the process of “commenting
out” portions of JavaScript code.
Explain the
primary rules for creating a JavaScript identifier.
Explain the
use of variable declarations and assignment statements with numeric, string,
and Boolean data.
Explain the
syntax for referring to a method or property of an object.
Explain the
issue of cross-browser compatibility as it relates to JavaScript code.
Describe
the creation and use of event handlers, including an event handler for the load
event of the window object and how the HTML and JavaScript sections work
together using the DOM.
Describe
how the process flow for form submissions works between HTML, JavaScript, and a
server-side language like PHP.
Response
Guidelines
Comment on
the post of at least two other learners. Offer insights, solutions, examples,
or opinions that add depth and value to the conversation.
Note
regarding discussions in this course: The discussion topic should determine the
length of your post, however, a minimum of 150 words is recommended. Refer to
the Discussion Participation Scoring Guide for post expectations. Make your
initial posts by Wednesday to allow time sufficient for peers to respond. The
expectation within the course discussions is to respond to at least two posts
by the end of the unit, but it is highly recommended that you extend the dialog
further. Responding over multiple days will help stimulate a lively discussion.
