What Are Coding Languages?

Coding languages are different ways of providing instructions to computers and programs. The same way spoken or written languages communicate information, so do coding languages. They allow programmers to instruct computers on what and how to do specific things.

There are dozens of different computer programming languages. A skilled software developer will use them to communicate with a system or terminal.

Moreover, programming languages are further distilled into “binary”. This is the base language that all computers understand. Binary consists of sequences of ones and zeros.

Each coding language comes with its own features, advantages, and disadvantages. What’s more, you can use different programming languages for different tasks. For example, HTML allows you to create web pages or instruct web browsers.

With Java, you can construct applications in game consoles, cell phones, and much more.

The different types of coding languages you learn through software developer training can affect:

  • What jobs you can hold
  • What type of coding tasks you can complete
  • What kinds of computer software you can make
  • And more

But no matter what, learning how to use coding languages in IT courses will benefit you. It can be a great boost to your resume and employment prospects.

In-Demand Coding Languages - Pitman Training

In-Demand Coding Languages

Learning any coding language is a huge benefit for your professional future. Yet, certain coding languages are more in-demand or desirable than others. Let’s take a look at the most in-demand coding languages. This way, you can prioritise your training efforts.


You have most likely heard of JavaScript before. That’s because it is one of the most common and popular coding languages. In fact, it currently stands at #1 in the world, according to Stack Overflow.

This client-side programming language runs inside browser programs. Browsers using JavaScript include Google Chrome, Internet Explorer, and Mozilla Firefox.

The interesting part, JavaScript processes commands on individual computers, rather than on servers. Because of this, JavaScript is usually placed into ASP or HTML files.

JavaScript is most often used by specialised developers. But, web developers and software engineers also make use of it.

The finance, healthcare, marketing, design, and engineering sectors often use JavaScript. They favor it because of its use in designing web pages that are easy for their customers to navigate. Organisations like WordPress, LinkedIn, and others rely on JavaScript.

JavaScript is easy to learn since it contains very basic features. It also operates on many frameworks. Plus, you can access JQuery, a public JavaScript library, to put together your own programs.

Although the names are similar, JavaScript is not related to Java.

HyperText Markup Language - Pitman Training


HTML stands for “HyperText Markup Language”. HTML is the standard coding language you can use to make web pages. In brief, it ensures web page text and images have the correct format. This is key so that Internet browsers can display them in the proper manner.

As a result, HTML has widespread use in many jobs, including web developers, software engineers, email designers, technical editors, and web designers. Apple and many more organisations use HTML. If you have ever built a webpage, you have also used it, if only a small bit.

HTML is a great coding language to learn since it’s very easy to understand. Despite its evident simplicity, HTML is versatile and flexible. And, it allows you to make many different web pages or elements. Once you know HTML, you can perform almost any web-based task.


CSS stands for Cascading Style Sheets. This programming language is often used in conjunction with HTML. If HTML is in charge of the organisation of the site, CSS is in charge of the aesthetics.

CSS is important because it manages the design elements of the site. This includes the size, color, and position of all the elements on the page.

Cascading Style Sheets - Pitman Training

The use of cascading in the name tells a lot about this programming language’s use. Once you choose an aesthetic element for the “parent”, it will cascade down to all the “children”. In other words, you do not need to repeat the code throughout the whole site. This factor makes CSS a convenient and popular programming language.

HTML, JavaScript, and CSS are often used together. These three programming languages allow you to create an optimal user experience.


This programming language is another that is high on the list of ‘must-have’ skill sets.

This object-oriented programming language is often used in the finance and e-commerce sector. These sectors favour Java because it is very secure and can handle a ton of data. Many big corporations use Java, including Airbnb, Google, and more.

Java is also popular because it is easy to use and quite easy to learn. There are also many open-source libraries that you can reference for help as you are learning it.

Another unique aspect of Java is that it is a cross-platform program language. Java can run on any operating system, regardless of where you write the original code. Thus, programmers call it a “write once, run anywhere” programming language. This also makes it ideal for use in app and game development.

Then there’s Python. Python is one of the most advanced programming languages in web developer training. It is object-oriented and built on flexible, robust semantic principles.

Python is often used by specialised Python developers, backend developers, and software engineers. Many other professionals in the information technology and engineering sectors use it, too.

Lots of major organisations use Python, including Google, Instagram, and more. NASA makes use of Python in some of its software for satellites and rockets, as well.

The major advantage of Python? It’s a perfect choice for rapid application development or RAD. That’s in part because it lets you integrate different systems fast. (Since it operates as a “glue” or scripting language.) In this way, Python lets you stream together different ideas or actions in a seamless manner.

Even better, Python is quite simple to learn and easy to read. It’s associated with many different web frameworks for developing web applications. So it’s perfect for combining with other languages such as JavaScript.

With Pitman’s Python course, you can become well-versed in this programming language.

Structured Query Language - Pitman Training


Last but not least, is SQL. SQL stands for Structured Query Language. It differs from the other programming languages above but is just as important.

While the others are third-generation languages, SQL is a fourth-generation language. It is not used for building websites, software, and applications as the others are. Instead, SQL is used for managing data in a database.

SQL is one of the few languages that databases understand. It is also the most popular among companies. Thus, it is necessary for developers and programmers to know how to work with it.

The finance sector often makes heavy use of SQL. For example, the payment system Stripe uses SQL to manage its database. Music applications like Spotify also use SQL to manage data. When the system recommends music to suit your preferences, this is with the help of SQL.

Almost any system you can think of that stores, retrieves, and works with data, uses SQL. Thus, SQL courses will boost your employment prospects.
