Maintaining JavaScript Security in Virtual Educational Environments It can be argued that JavaScript is one of the most important coding techniques in today's modern websites. If you're involved in any part of website design, construction, implementation, or maintenance, then it's almost a requirement that you have at least a basic knowledge of the topic, and it's even helpful if you're an advanced user.

Specifically within the realm of educational environments, JavaScript plays an important role particularly because of privacy issues, which is why it makes sense to pay attention to things such as keeping your e-mail secure, reading about JavaScript tricks, learning how code security affects browsing, avoiding website hacks in general, and thinking about teacher and student privacy matters as well.

Keep Email Secure

When it comes to teacher and student e-mails, it's important to note that a certain amount of security should be adhered to. Typically this is going to come in the form of something like keeping emails encrypted to avoid any sort of loose information. Within e-mails themselves, standard practice is to avoid JavaScript completely, as e-mail clients can either erase it completely or render it to a disabled state.

Read About JavaScript Tricks

One of the things that you'll run into when you're learning about JavaScript are how to write some common tricks. These are ways to keep code cleaner and more simple, even though you have to understand some internal processes a bit more clearly. Within the academic realm, it's no surprise that educators try to incorporate these methods to keep everything clean and concise.

How Code Security Affects Browsing

When you think about what top-quality college websites look like, you're mostly likely looking at a combination of excellent web design and HTML mixed with a fair amount of JavaScript. You'll notice that if you disable JavaScript in your browser, these sites don't have nearly the power, and may even not be functional. But sometimes, you must enable JavaScript in browser for better experiments.

Avoiding Website Hacks

One of the common ways that websites get hacked, including educational ones, is through JavaScript obfuscation. When this happens, what looks like garbled code will be calling scripts into play that can do any number of malicious activities onto the site. Educators in particular have to watch out for these sorts of hacks because administrators are often more interested in simple presentation of information rather than making sure their sites are airtight in terms of coding.

Thinking About Teacher and Student Privacy

Teacher and student privacy is of the utmost importance, and when you look around in forums to see why people turn JavaScript off specifically, it's for privacy and security reasons. That should give you some indication of the balance that you should aim for as a JavaScript developer, especially in the academic realm, as you want to make sure everything is function but also secure.
