HTML is great. It defines the structure of webpages and it determines how data is displayed online. What you’re looking at right now is HTML code, read and interpreted by your browser. But this doesn’t make HTML a programming language.
A Markup Language
HTML is a type of markup language. It encapsulates, or “marks up” data within HTML tags, which define the data and describe its purpose on the webpage. The web browser then reads the HTML, which tells it things like which parts are headings, which parts are paragraphs, which parts are links, etc. The HTML describes the data to the browser, and the browser then displays the data accordingly.
That’s how the browser knows that
This is a heading
This is a paragraph, and
However, this is not programming. The above is not an example of an executable script. The HTML was only used in the above to mark up the text for the browser to read and interpret as web page content. It told the browser which parts where headings, which were paragraphs, and which were links, and the browser displayed them as such. HTML is used for structural purposes on a web page, not functional ones.
Not a Programming Language
Programming languages have functional purposes. HTML, as a markup language doesn’t really “do” anything in the sense that a programming language does. HTML contains no programming logic. It doesn’t have common conditional statements such as If/Else. It can’t evaluate expressions or do any math. It doesn’t handle events or carry out tasks. You can’t declare variables and you can’t write functions. It doesn’t modify or manipulate data in any way. HTML can’t take input and produce output. Think of it this way: you can’t compute the sum of 2 + 2 in HTML; that’s not what it’s for. This is because HTML is not a programming language.
Unfortunately, coding only in HTML doesn’t make you a programmer. In fact, HTML really shines when you use it in conjunction with an actual programming language, such as when using a web framework. That’s when you can start serving up dynamically created web pages and database applications.
But don’t worry, even with pure HTML, you’re still a coder. You’re writing lines of code in a (markup, not programming) language. You’re essentially codifying information for the web. So while you might not want to put HTML on the “Programming Languages” part of your resume, you should definitely have it under “Skills”, or simply “Languages”.
Knowledge of web page structure is a valuable asset for anyone to have, in IT as well as in other fields, and I’m definitely not trying to discredit anyone’s knowledge on the awesomeness that is HTML. HTML is a core tenet of front end web development and is obviously a major aspect of what the user winds up seeing on their computer screen. With the emergence of HTML5, HTML’s capabilities and opportunities to define and structure web page data have soared to new heights, with a greater emphasis on multimedia, mobile web, geolocation, and more. This makes a solid understanding of HTML even more useful to have.
So keep rocking the HTML, get to know it well, and by all means, code away! Just don’t call it programming.
Still think HTML is a programming language? Think “programming” and “coding” is all just semantics? Let me know in the comments.
