Learning Computer Language Easily
JS is another term used when describing the programming language designed by the Netscape Company; also known as javascript. This language, which is a compilation of both symbols and numbers, is used to allow the performance of certain functions on a website. The language is written into a website’s HTML code, which allows a specific action to be initiated when a certain action is performed by a website user.
There are different types of JS that perform different functions. Different types of javascript are created when it is combined with other languages, such as when cascading style sheets are combined with javascript to form CSS javascript. The new combination is able to create bold effects when used in dynamic HTML active scripting. A second example of this is PHP javascript; when javascript is combined with a hypertext preprocessor script. The disadvantage of this type is that the javascript leaves no room for error, and will only be displayed correctly if all information is input correctly.
When an Internet user makes their way around the internet by clicking links and interacting with the information on different pages, menus written in JS are triggered. Websites utilize javascript to allow clickable links to open up new pages to show information. While this is a very common use for javascript, it is not the only one. Javascript is also used to make images and text appear when the user rolls their mouse over certain areas of web pages. Another action that javascript is used for is to initiate the activation of annoying popups.
Being able to disable popups and the associated javascript can be very useful for many reasons. One is the fact that it can help keep down the amount of viruses that can infect a user’s computer. If a virus is maliciously written and hidden into the HTML code, such as when JS is needed to close a pop up box, then disabling javascript will stop the virus from infecting the user’s computer. This new trend of dropping a virus on a computer is called click-jacking. The virus is written into the script and is activated when the user attempts to close the popup ad window. Disabling the javascript for this reason alone can be extremely useful. Disabling javascript can, of course, stop pop ups from opening in the first place. This is not only perfect for those times that a virus could infect the computer, but also to keep the amount of browser windows that open automatically down to a minimum.
