JavaScript vs HTML 


JavaScript vs HTML 

Many different coding languages may be used to create websites, some of which are more complex than others. The most widely used programming languages for creating websites include HTML, JavaScript, CSS, Python, Ruby, and SQL. The fundamental languages of HTML and JavaScript enable you to comprehend web design and development basics.

Let’s explore how JavaScript and HTML differ from one another.

JavaScript vs HTML


The JavaScript program code is used for creating websites, games, and other applications. You can add dynamic elements to web pages with it that are impossible to do with only HTML and CSS alone. JavaScript is a programming language supported by many web browsers and used to run dynamic web content. 

You can see the effects of JavaScript whenever you see a drop-down menu that you can click to reveal more material that has been added to a page or dynamically changing element colours.

If JavaScript is not used, you can only create a static website with colours, words, images, and links. There will be no functioning upload/download, search, button, file, or other capabilities. All browsers have built-in JavaScript support engines because of JavaScript’s important role in web development. Because no additional programs need to be installed, it is convenient for programmers to utilise.


HyperText Markup Language, or HTML, is a widely used markup language for building websites and software. All web page content is built on HTML, which also affects the layout and structure of your page. Along with CSS and JavaScript, HTML is a front-end development language.

One of its main advantages is that HTML is inexpensive and doesn’t require any special software. Since HTML doesn’t require any plugins, users shouldn’t have to deal with the many add-ons needed to operate any software.

Among all of the computer languages on the market, HTML has one of the friendliest search engines. Compared to other computer languages, HTML is extremely simple to use when creating SEO-compliant websites.

Here are some standard differences between HTML and JavaScript. 

Standard markup languages like HTML provide website structure.JavaScript is used to create more interactive and dynamic websites.
When HTML is rendered from the web server, the markup code is handled by the server before being transmitted to the client browser. Client-side scripting in JavaScript is synchronous and single-threaded, so all written code is assembled and executed within the web browser. 
Because HTML pages are static, their content cannot be altered.JavaScript can modify content to produce dynamic web pages.
HTML outlines the fundamental layout of a web page.JavaScript enhances web pages’ interactivity to make them look beautiful.
HTML is cross-browser compatible, which means it functions well with every web browser version. It is simple for older web browsers to manipulate unidentified HTML components since both old and new browsers treat unrecognised elements as inline elements by default.A few functions of JavaScript are incompatible with some browsers because of its lack of cross-browser compatibility.
HTML requires CSS to format and present the data in an organised manner.JavaScript integrates dynamic functionality into HTML code to display it.
Maintained by the WHATWG and W3C. Maintained by ECMA TC-39 committee.
You can use any browser to run code.A JS engine is required to run code.

Is JavaScript Better than HTML? 

JavaScript and HTML are like two sides of the same coin. They are like poles apart from one another, but they are connected by a string. 

HTML is a markup language that current browsers can comprehend and employ to render web pages. It is essentially the foundation of any web page.

On the other hand, JavaScript is a front-end language that is mostly used to alter the contents of websites that were developed using HTML. It is a scripting language that runs entirely on the client side, independent of the server.

Since both languages offer different functions, there is no direct comparison between JavaScript and HTML. 

Should I Learn JavaScript or HTML first?

Ideally, you should learn HTML first and then JavaScript because HTML is the foundation of creating websites, while JavaScript is used to enhance the developed websites. 

Reasons Why You Should Learn HTML Before JavaScript 

  • Every website is built on the foundation of HTML.
  • Making responsive designs requires HTML.
  • It’s harder to learn JS without HTML.
  • Full site functionality is ensured by HTML knowledge.
  • JavaScript is built on HTML.
  • You get a chance to become a better web developer with HTML skills.


JavaScript is frequently recognised as one of the most inventive programming languages used to add dynamic content to websites by modifying the page content. HTML is a collection of codes placed in a file to organise a webpage, whereas JavaScript is a more high-level language that makes a website seem dynamic.
