Java script is an easy to use programming language in can be inserted in the header pages of your websites. The java script improves your website performance greatly. The interactive features of WebPages allows you to perform calculations, validate forms, create online games, special effects, graphics, security passwords and many more. There is not much difference between java and java script. The syntax is also same for both languages. But, Java is an object oriented programming language which is designed to create applets or stand alone applications. Javascript is much simpler version of the java, and it is widely used to create scripts for the web applications. Java script is a useful feature rich powerful code used by many programmers and web developers. In this article, we shall discuss some of the advantages and disadvantages of using Javascript in the web design. Javascript is a popular browser based language that actually runs on client side. Javascript codes are bundles along with the WebPages and delivered to the clients. The codes run from the clients web browsers and do not require server to run the scripts. Since it is a client based function, the execution o the code is faster. This is one of the great advantages of using java script in web site development. Validating input forms is another great advantage of using Javascript in web development. When a user fills up some web registration forms he may miss out some fields or certain fields need to be validated such as date, selecting region or age. If server has to respond to each of the above request it consumes lot of time and puts more pressure on the bandwidth usage. But using java script this can be executed in the client browser itself. You can set field like input data; range from and validate form fields. If user forgets to miss some fields, you can create some Javascript to remind the user to fill the fields. This reduces the number of requests to the server and helps in more interactive and faster web applications. The next area where the Javascript found useful is in the creation of dynamic effects. We can create some rollover images and scripted slideshows to make your website more intuitive. By using Javascript effectively, we can chance the appearance of the end-user screen. This creates customized effect on the client WebPages with impressive and dynamic screen effects. Javascript is simple to learn and implement in any web pages. It is more flexible and versatile to use in any language platforms. Unlike PHP or SSI scripts, it can be embedded to any web pages. It supports all file extensions. Since it is a client side coding it reduces the number of server request there by delivering faster results. Some disadvantage factor for using Javascript is security and tendency to bloat web pages. The client side coding advantage is considered as a severe security lapse by many programmers. Any user can view the code and can manipulate it easily. In some cases, it can be misused by hackers. Many web browsers come with options to disable Javascript to ensure security. It is estimated that about ten percent of web users disable Javascript in their web browsers. The tendency to blot can adversely affect your website search engine friendliness. When search engine looks for quality content and keywords in your web pages, it can crawl hundreds of lines of Javascript codes. This issue with the Javascript can be easily rectified by sorting the java scripts as a separate .js files and linking them with the HTML pages. Another disadvantage of using Javascript is interpretation. Modern net users do not stick to single web browsers. They change and adapt to new kind of browsers that are available in the internet. The main difficult is that not all the browsers interpret the codes correctly. Some browsers do not recognize the Javascript codes. The mobile devises and some applications find it difficult to decipher the Javascript codes successfully. You do not have any translation problem with the server side codes, since all the server side codes interpreted correctly by any browsers in the internet. This is not happening when we employ client side coding elements like Javascript. But it is difficult to figure out the exact code which matches all the requirements of the browsers. The only way to make sure that Javascript runs perfectly is to try in possible number of browsers that are available in the market. At the minimum, the developer has to test the scripts in popular/leading web browsers. Javascript is an excellent client side scripting tools that can be used to maximize the website performance and minimize the server request. Employing some standard and secure programming methods, we can effectively use this master script to create interactive web sites for the end users. Have a freelance job? Want a freelancer job?
