Coding is the language of the digital world. In the last few decades, code has been fundamental in revolutionising tech. We use code to write programs that power the software that enables devices, apps, and websites to run properly – things we interact with at every moment of every day.

In what’s been called the Fourth Industrial Revolution, every industry is becoming a tech industry. The foundation of the new digital world is built on the shoulders of code, software, and programs that help industries from healthcare to agriculture operate. 

In short, businesses increasingly rely on tech that is built by code to function properly. As technology continues to evolve, the demand for skilled coders and software engineers will only grow. This article is a deep-dive into the importance of code in the Digital Age, making the prevailing argument that everyone should learn to code.

What is Coding?

In the simplest terms, coding is the language that we use to speak to computers. You can think of code as operating instructions that devices follow in order to do their jobs.

From AI and VR straight through to software and web applications, coding offers countless opportunities to create in the digital age. Web developers use code to develop and implement websites. Data scientists use code to write algorithms that analyse data. Software engineers use code to build algorithms that teach AI how to learn, or to write software that helps computers run. 

Code is truly all around us. It helps society function.

Importantly, coding isn’t just about memorisation; it is a creative process that involves high levels of advanced problem-solving and critical thinking skills to get just right.

Coding vs. Programming

As you dive into the world of code, you might hear the terms ‘coding’ and ‘programming’ used interchangeably. While they are largely similar from a zoomed out perspective, there are subtle key differences between the two terms.

Coding is the act of writing code, or the set of instructions that tell a computer what to do. When you’re writing lines of code and building the structure of your project, you are coding.

Programming is the overall process of creating a software program. It is the process of designing, writing, and testing code to create a specific program for a specific purpose. Programming often involves the following steps:

  • 1. Designing the program: First, you define the purpose of the program, choose what features it will have, and think about designing the user interface.
  • 2. Writing the code: This is the coding process, where you write the actual code that will implement the program’s design from step 1.
  • 3. Testing the code: Then, you check for errors. You’ll run the program and, if you notice any bugs (errors), you fix them.
  • 4. Deploying the program: Finally, once the program is designed, written, and tested, you then make it available to users.

In summary, coding is part of programming, while programming is a more comprehensive process that includes designing, coding, testing, and deploying software.

Coding Languages

As you may know, computers use a binary system of long chains of 1’s and 0’s to “think.” Programming languages were developed to help translate those chains of 0’s and 1’s in a way that is easily understood by people.

A coding or programming language is an organised, universally accepted way that programmers can give a set of instructions to a computer or system to execute. It’s a way of translating thoughts into action, from human to computer.

There are many different coding languages in use today, each with its own unique applications and functions. As with most things, as code gets more complex, the functions it will be able to perform will also become more complex. Some of these coding languages include:

  • Python: This is a general-purpose language that is pretty easy to learn and use. You’ll find Python in data science, machine learning, and web development most often.
  • Java: The key factor that makes Java stick out is its stability and security. People often use it for enterprise applications and mobile development.
  • C / C++: Both of these languages are very powerful and are typically used for low-level programming. They are often used for operating systems, embedded systems, and game development.
  • JavaScript: This scripting language is used to add interactivity to web pages. It is also used in game and mobile development, too.
  • Swift: A newer language, Swift is designed to be user-friendly. It is easy to learn and use, and is most often used in either iOS or macOS development.

There’s also an honourable mention to HTML and CSS. While these are not technically programming languages, they are a means for web developers to help structure the page and add style information. Before moving on to more complex programming languages, HTML and CSS is where your knowledge begins.

The best coding language for you will depend on your needs. If you’re new to coding, you might start first with HTML and CSS, and then move on to Python or JavaScript. Once you’ve gotten a grasp for how coding works, you can then explore other languages that are more specific to your needs.

Careers in Code

The last few decades have seen coding explode as a desired and necessary skill across industries. Learning to code opens the door for many lucrative, creative, and in-demand careers, and demand is only projected to grow in future.

Front-end developer

A front-end developer writes code for webpages. They typically are the ones who configure the user interface (UI) and user experience (UX) of a website or app. They use HTML, CSS, and JavaScript to build visual and interactive elements that users see on webpages.

Back-end developer

Back-end developers build and maintain the servers that power a website or app. Using Java, Python, or Ruby, they build the logic that translates to functionality on the front-end of a website or app.

DevOps engineer

They manage the infrastructure and deployment of a website or app. Their job is to automate the development, testing, and deployment of processes to ensure that software is build quickly and precisely.

Full-stack developer

When you’re “full-stack,” that means that you can work on both the front-end and back-end of software development. They are the all-rounders, working on anything from UI to server logic in a website or application.

Quality assurance engineer

As the job title suggests, they ensure the quality of the code of a website or application. They work to identify and fix bugs and to make sure that the software is working properly according to the goals of the project.
