You have often seen a pop-up that comes on your computer screen which stated you need to run Java or update JavaScript. Many people get confused between these two and wonder what’s the difference between the two, Java and JavaScript.
What is the use of JavaScript?
JavaScript is usually used to make interactive web pages. It is not required to download JavaScript continuously when browsing a website; it runs automatically on your computer system. As a result, the user experience on your site will be faster and better. You can use JavaScript to create quizzes or polls and anything else that will promote visitor interactions. The main endeavor of using this program is to produce an interaction between the site and the visitors and so making them spend more time on the site to create an engagement that is not limited to just visiting the website.
How different is JavaScript from Java?
Java is a computer programming language that is used to generate applications that need to be run in a virtual machine or browser. It allocates programmers to write computer instructions in English instead of the numeric code that is generally 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 Google chrome, IE, or Firefox, you will most likely need nothing special to run JavaScript. All these browsers cited above already have the support built into them. However, this will work only if your system is JavaScript enabled and has a browser that supports it. If it is, then the JavaScript will automatically run anytime someone visits the website.
You probably don’t need to take up any special class or training to run JavaScript, but it’s always best to have an idea how to use it. 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 dissimilar and have different purposes, features and capabilities. JavaScript is a programming language that can perform dynamic tasks while HTML is designed to create static web page content. 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.
JavaScript is not hard to learn but not everyone who owns a business is versed with it or at least know how to apply it. If you use JavaScript to build your website, it can only benefit your site by adding various aspects to it. Hence, it would always be helpful if you can hire a professional web designer who is familiar with JavaScript programming.
