Javascript

Javascript is a programming language that is normally used to make websites more interactive. The main advantage that Javascript offers over other means of adding interactivity to a website is that it runs locally in the browser. This means that it is much faster than other methods of accomplishing the same thing. Javascript was originally created to improve the interactivity of web browsers; however it soon became obvious that it was also useful in adding elements to a webpage. The most common uses for Javascript are to do things like validate the information that is entered onto a web form or changing images as you move your mouse over them. There are far more complex things that can be done as well if the programmer has the required skills.

The biggest reason for the popularity of Javascript is the fact that you can imbed the code straight into an HTML document. That makes it very simple to add elements to a site without having to completely rewrite the code. This not only helps to make it much easier to build your sites it also helps with your search engine rankings. One of the problems with most dynamic sites is that they don't rank well in the search engines. This is because the search engines are looking for sites that include HTML; it's what they expect to see. If your site doesn't include HTML it is unlikely that it will rank well in the search engines. With Javascript you can build your site with HTML which appeals to the search engines and at the same time you can add the elements that you need to your site.

One of the most confusing aspects of Javascript is the name. Most people would naturally draw the conclusion that it is related to the popular Java programming language. In fact this is completely untrue; the two languages have almost nothing in common. There is a lot of debate as to just why they would choose to apply a name like Javascript but it does seem to be clear that they were trying to take advantage of the popularity of the Java language. Whatever the truth behind the name Javascript has become a very popular and very useful language that has greatly increased the capabilities of web designers.

Over the years Javascript has developed something of a bad reputation amongst programmers. A lot of that had to do with the fact that Javascript was mainly being used by amateur programmers to build websites. This tended to result in the professional programmers looking down on the language. There is also the issue that a lot of people find Javascript to be a rather bulky and inelegant language. Nevertheless it is a useful language that can do things that couldn't otherwise be done. For the most part even the programmers who dislike Javascript have found it necessary to use it.
