HTML first version was introduced in 1993 and it simply displayed plain text on a webpage. JavaScript was invented in 1995 to give more flexibility and add functionality to web pages.
In this post, we will discuss both JavaScript and HTML along with answering the question of what is the difference between JavaScript and HTML.
HTML
HTML is a hypertext markup language that gives our web pages structure and allows us to display plain text. Every web developer knows HTML and it’s the first step that a beginner developer takes to learn web development. HTML has elements, also called tags, that tell our browser how to display the content of our webpage. Let us view a simple HTML webpage:
<html lang="en">
<head>
<title>Document</title>
</head>
<body>
<h1>Heading</h1>
<p>Simple Webpage in HTML</p>
</body>
</html>
The output of this code will look like the following:
JavaScript
JavaScript is a proper high-level programming language that gives our web applications and web pages the ability to think and act by making them interactive and dynamic. JavaScript is used for validation, manipulation, and calculation of data and the best thing about JavaScript is that it can be used on the server-side as well as the client-side. One common example of JavaScript usage will be the Amazon Search bar where you search for an item and the item is displayed. This functionality is programmed in JavaScript. To put it simply, JavaScript improves the user interface of the webpage and makes a web page interactive hence enhancing user experience.
A simple example of JavaScript is given below where are initializing a variable and then we console log that variable:
Difference between JavaScript and HTML
- HTML gives structure to our webpage whereas JavaScript makes our webpage dynamic and interactive.
- HTML is a markup language whereas JavaScript is an advanced programming language.
- HTML uses tags like <h1>and <p>to define or manipulate text which is limited whereas JavaScript offers inbuilt functions where we can manipulate and define data.
- HTML works on all browsers whereas JavaScript is not compatible on all browsers and when the version changes as well as it requires a JavaScript engine to run the javaScript code.
- HTML shows the same content to every user and cannot interact with the user whereas JavaScript can show content to a certain user and can interact with the user.
- HTML static material is shown on the server-side, whereas JavaScript programs are performed on the web browser’s client-side.
- HTML allows embedding of JavaScript within however JavaScript doesn’t allow HTML embedding within.
- HTML is maintained by W3C and WHATWG whereas in the JavaScript case, it is maintained by the ECMA TC-39 committee.
- HTML contains no supporting libraries to further improve the appearance of the webpage whereas JavaScript has various libraries like React js, Angular js which add more functionality to improve our web application or webpage.
Conclusion
HTML is a hypertext markup language that is older than JavaScript and plays with the manipulation of plain text and provides static structure to our webpage. JavaScript is an advanced web programming language that makes our web applications and web pages dynamic and interactive. To put it simply, HTML specifies how a web page should appear, whereas JavaScript enables you to interact with web pages.
In this post, first, we defined what HTML and JavaScript are and then went on to answer the question of what the difference between HTML and JavaScript is.
