It is been long time since the first website
published. In recent era, JavaScript might not popular term, but still the main
development of internet technology. Many people cannot make clear distinction
between java and JavaScript. You will know about such matter in the following
part. Regarding JavaScript new development, HTML takes much advantage. You
cannot develop JavaScript without html and vice versa. The reason is also
presented on the following section.
Understanding
Script Language JavaScript
Java vs. JavaScript is what
everyone what to know, especially for beginners. Java is programming language
to create standalone application. For example, programmer creates application
to check the weight and calorie that can be installed in mobile device or
laptop. Java is similar to Python or C, but in different properties. Java is
object-oriented program.
JavaScript is more like text-based language.
Development of JavaScript started from Netscape as one of browsers in early
internet era. JavaScript cannot be placed without HTML. Read the word “script”
behind java. This means JavaScript does not need compiler to run. You just
write this script in Notepad with HTML language. After that, save into htm
extension then run through the browser. Script
language JavaScript is simple and no complex structure. It can be
attached or detached based on your preference and need. JavaScript, HTMLL, and
CSS are the the top used technology for website and browser. Compatibility of
JavaScript will be explored in the next section.
JavaScript security has huge
concern this day due to vulnerability of cross scripting. As you know, JavaScript
makes website to be more interactive. Moreover, JavaScript is integrated into
HTML, which increases the risk. You already know that virus is one of
JavaScript products. Malwares and viruses incorporate JavaScript to embed into
website and browser. When you hit certain link, this virus activates to be automatically
installed in your system. Every technology has benefit and risk. In spite of
high risk, JavaScript is excellent protection to keep website from unwanted
penetration. Web developer fights against malware and virus with the same
language.
JavaScript is heavily utilized in website and
browser. As you know, static website only provides non-interactive content.
Viewers only read and there is no interaction from visitor side. JavaScript
changes everything and makes it more interactive with comment, picture, video,
even form submission. Browser compatible is
important in this matter. Since the beginning of internet era, you will find
many browsers. Few of them are known today. The rest of browsers had been
discontinued. JavaScript is not static technology, so browser should match with
its development. Today, popular browsers with JavaScript support are Google
Chrome, Firefox, and Safari.
For programmers, it is important to know
whether bowser is compatible or not with this code. Can
a browser handle my script? This question is simple but quite tough to
answer. When creating script, you need to determine which browser that’s not
compatible. Normally, common and standard browsers are able to support recent
JavaScript. However, you may find niche users, which use specific browser. If
your target is this market, try to update browser and see what happen in
script. When the script does not run properly, it is time to check the code
structure.
Example code JavaScript:
<script type="text/javascript">
document.write("<h1>Ini Judul</h1>");
document.write("<p>Ini Paragfar.</p>");
document.write("<p>Ini paragraph yang lain.</p>");
</script>
Example code JavaScript:
<script type="text/javascript">
document.write("<h1>Ini Judul</h1>");
document.write("<p>Ini Paragfar.</p>");
document.write("<p>Ini paragraph yang lain.</p>");
</script>
