HTML5 vs JavaScript

Differences Between HTML5 vs JavaScript

HTML5 is the latest (i.e., fifth and current major version) and the most enhanced version of HTML used to structure and present content on the WWW (World Wide Web).

HTML5 released in October 2014 by W3C (World Wide Web Consortium). It is published to improve the language to support multimedia features by replacing HTML versions– HTML 4.01, XHTML 1.0, and XHTML 1.1. There is a misconception about HTML5 as it is a programming language, but it is rather a markup language to structure and present web content on WWW.

The new standard incorporates HTML5 features. Some of the important features are video recording & playback and drag-and-drop options which were had dependent on third-party browser plug-ins such as Microsoft Silverlight, Adobe Flash, and Google Gears.

Almost all versions of browsers support HTML5 features/functionalities like Google Chrome, Mozilla Firefox, Apple Safari, and Opera.

Advantages

Below are some of the Advantages of HTML5:

• HTML5 is very simple and have clear syntax,
• It supports Multimedia Elements,
• It has the feature – Accessing User Geographical location,
• It allows Client Side storage and Client-Server Communication, etc.

Javascript is dynamic scripting & interpreted programming language to build the behavior of web pages. Javascript is a lightweight, proto-typed and multi-featured language.

Javascript is made its first appearance in December 1995 to the world, and it was called by the name “LiveScript”. Since Java was huge booming and popular at that time, later, LiveScript is renamed with “Javascript” when it deployed in Netscape Navigator.

Javascript is an interpreted and high-level programming language with object-oriented capabilities.

The programs which are used in Javascript language are known as scripts. These can be written on the HTML page, and also these execute automatically as the page get loads—the purpose of the language embedded in Internet Explorer, Netscape and many other web browsers.

Javascript is provided and executed as plain text. It doesn’t require any special preparation to run. Javascript is one of the essential parts of web applications. It is one of the three core technologies of the WWW (World Wide Web).

Below are some of the Advantages of Javascript:

• It has very less server interaction
• It provides immediate feedback to the user/visitor if the user missed entering some information.
• It provides to create interfaces to increase the interactivity of the user.
• Provide many features like Richer interfaces like sliders, drag-and-drop options, etc.
• Browser Detection, Cookies, Control Browsers and Validate Forms, etc.

Key Differences Between HTML5 and JavaScript

Below are the lists of points; describe the key Differences Between HTML5 and JavaScript:

1. HTML is a Markup Language of the web, whereas Javascript is a most advanced, dynamic scripting & interpreted programming language.
2. HTML5 is used to create the basic structure and presenting content in WWW, but Javascript is a fundamental part of HTML5.
3. Web pages that are created with HTML define different elements present in a web page, whereas Javascript is used to define the interactive elements of a webpage which help to engage users.
4. The server interprets web pages as a graphic interface that is written in HTML5. But Javascript is actually a web version of actual programming code, meant to write applets for use on those websites.
5. HTML5 is used to prepare the text, and hence that it can be displayed on a web browser. There are no constructs of language. But Javascript runs in the context of a browser using by a user. It can be run with server-side JavaScript.
6. Javascript is faster compared to HTML5 since it need not to communicate with the Server and wait for responses back from it, where HTML5 needs to communicate and wait for its response.
7. HTML5 is more secure and scalable compared to Javascript since the code for the application will be written on the server-side, whereas in Javascript, code written will be in a database called as Ajax applications.

HTML5 and JavaScript Comparison Table

Below is the Comparison table between HTML5 and JavaScript.

Basis for Comparison	HTML5	JavaScript
Definition	HTML5 is a Markup Language of the web.	Javascript is a most advanced, dynamic scripting & interpreted programming language.
Usage	HTML5 is used to create the basic structure and presenting content in WWW. Web pages that are created with HTML define different elements present in a web page.	Javascript is used to define the interactive elements of a webpage which help to engage users. Javascript is a fundamental part of HTML5.
Elements used	HTML5 markup language includes a header, headings, titles, footer & video, anchor tags, img tags, audio tags, etc., in a program.	Javascript is an OOP scripting language and uses C programming like functions & uses only var data type.
Functionality	Web pages are interpreted by the server as a graphic interface written in HTML5. HTML AND CSS are used for website presentation.	Javascript is actually a web version of actual programming code, meant to write applets for use on those websites. JavaScript is used to change the behavior and dynamic content of the website.
Purpose	HTML5 is used to prepare the text, and hence that it can be displayed on a web browser.  There are no constructs of language.	Javascript runs in the context of a browser using by a user. It can be run with server-side JavaScript.
Faster	Since HTML5 need to communicate with the server and wait for its response, it is lesser faster, and hence it feels more suitable for desktop applications.	Since Javascript runs on a browser that doesn’t require communicating with the server, it is faster and feels more user-friendly.
Security and scalability	HTML Code is written on the server side and provide more security and scalability	Ajax applications are the databases with which Javascript communicate In the application which Javascript used will communicate directly to the database – Ajax applications, which provide less security and scalability.

Conclusion

If code written in Javascript makes the application faster and meanwhile it is less secured and scalable. Suppose code written in HTML is more secure and scalable. Since code written using Javascript need not communicate with a server (directly communicate with a database), it makes it faster and as well less secured. Hence it is always recommended to have knowledge of both HTML5 and Javascript to build a beautiful, secured and scalable website.
