Basic Languages For Front End Web Development


Now, it is very important to realize that there is a range of different languages that are used for web development. As noted above, front and back-end developers will need to learn different languages, while full-stack developers will need a working knowledge of all the major web development languages.

With this in mind, we have put together a list of some of the most common languages for web developers to learn, along with an explanation of what they are used for and how you can learn them.


HTML


HTML is an essential language if you want to understand what is a web developer and how to become a front-end one. To explain it fully, I need you to do something for me: Right-click on your browser window, and select ‘view page source’. You should be taken to a new tab containing all of the information which goes into the creation of this webpage.

What you are seeing is mainly HTML code. It tells the website what content to display and to some extent, how to display it. At the top of the page, on the first line, you will see the command. This tells your web browser to expect HTML code.

If you explore further, you will start to recognize things on the page. You will see some commands that you understand, such as ‘link’, ‘image’, or ‘video’. These are all content commands which tell your browser what to show, where to get the content from, and how to show it.

HTML is a very easy language to learn, and it is usually the first one learned by new programmers. If you are interested in exploring HTML, having a deeper look at what is a web developer, and front-end web development, consider enrolling in the beginner HTML course.



CSS


CSS is the second of the essential front-end languages and is also one that every front-end developer must be fluent in. The CSS code is used in conjunction with HTML. While HTML tells the webpage what content to display, CSS tells the webpage how to display the content - it’s a ‘styling’ language. Once you have learned CSS, you will be able to do a wide range of things, including:



As you can see, CSS plays a big role in web development, especially to front-end developers. If you would like to learn CSS, try the Introduction to HTML and CSS course, which will teach you the basics of both HTML CSS. Alternatively, try Interactive Coding for Beginners, which will give you an insight into the basics of HTML, CSS, and responsive web development.



JavaScript


What do web developers do? Well, most web developers take a programming language like Java or HTML and use it to create a component of a website. JavaScript developers are no different, except they create very specific content. So, for JavaScript, what is a web developer exactly?

Most JavaScript developers work on the front-end of a website. They build small snippets of JavaScript code that make your website responsive, interactive, and attractive to your visitors. These JavaScript snippets are often embedded in the HTML source code for a website.

Although it has traditionally been a front-end language, and one which is vital for any front-end developer to learn, JavaScript is becoming increasingly popular for back-end development as well. A lot of front-end developers are beginning to find work as full-stack developers due to their knowledge of JavaScript, which means that its usage and popularity is skyrocketing.

If you're looking to learn JavaScript and are a beginner, I'd recommend this edX's course. However, if you already have some prior knowledge, you would benefit from this intermediate JavaScript course.
