What Is JavaScript?

Many of us have often seen a pop up come on our screen which says we need to run Java or update JavaScript. Most of the people get confused between these two and wonder what the difference between Java and JavaScript is.

What is the use of JavaScript?

JavaScript is normally used to create interactive web pages. JavaScript will run on your visitor’s system and you will not be required to download it continuously on your website. As a result, the entire user experience will be faster and smoother. If you are a visitor to a site, you will notice that JavaScript is normally used to create quizzes or polls and anything else that will encourage visitor interaction. The main aim of using this program is to create an interaction between the site and the visitor and create an engagement that is not limited to just visiting the site.

How different is JavaScript from Java?

Java is a computer programming language that is used to create applications that need to be run in a virtual machine or browser. It allows programmers to write computer instructions in English instead of the numeric code that is normally used. JavaScript is just an object oriented programming language code which can only be run on a web browser.

What is required to run JavaScript?

If you use one of the major browsers like IE, Firefox or chrome, you will not need anything special to run JavaScript. All these browsers will have the support built into them. However, this will work only if your user has a browser that supports JavaScript and it has JavaScript enabled. If it is, then the JavaScript will run automatically when someone visits the site.

One may not have to take up any kind of training to run JavaScript. This code is prewritten and will be easily available as a plug in. The JavaScript will run automatically if the user’s browser has JavaScript support and it is enabled.

What are the requirements to write JavaScript?

There are no special codes to create JavaScript. This is because it is an interpreted language. Notepad or any other similar plain text editor can be used to create the language.

Can designers use HTML instead of JavaScript?

HTML may not be used instead of JavaScript. Both these programming languages are completely different and have different functions, features and capabilities. While HTML is a markup language and is designed to create static web page content, JavaScript is a programming language that can perform dynamic tasks. It can be used again and again on different pages of a site. This can be done by externalizing and placing it in separate files and linking a JavaScript file to the HTML code of the particular page. Hence, JavaScript can be added to many pages by adding the correct tags on each of the pages.

Not everyone who owns a business may be well versed with JavaScript or know how to use it. Using it to create your site can only benefit your site because of the various aspects that JavaScript can add to it. Hence, it would always be helpful if you can hire a professional web design company who can help you build your site using JavaScript. The team of professional designers can sit with you, understand your business and design a site keeping all your business needs in mind.
