What is coding and what is it for? A beginner’s guide


Coding makes it possible to access and interact with websites – even this one. But how does coding work?

Software programming or computer programming involves writing instructions to communicate with machines. All devices –– laptops, desktops, phones and tablets –– depend on code to function.

The coding also manages the cities. Computers operate traffic lights that have been programmed to perform certain operations. Even astronauts on the International Space Station must know how to code. Coding offers many career opportunities in technology and beyond.

What is coding?

Every website and application works because programmers write code. However, you don’t have to be tech-savvy to use coding. In fact, job seekers can find most coding jobs outside of the tech industry. What can you do with the coding?

Learning to code is the foundation for lucrative career opportunities. Bootcamp graduates may need to gain experience as junior developers before earning six-figure salaries.

The coding career you get depends on your work experience, education, and knowledge of programming languages. Coding prepares you to launch a career as a web developer, game developer, computer network architect, and computer system analyst. The Bureau of Labor Statistics predicts that computer and technology jobs will increase at a rate of 13% from 2020 to 2030.

However, employment growth varies by occupation. Computer programmers, who earn a median annual salary of $ 89,190, will see an expected 10% drop in jobs. Applicants with a bachelor’s degree or higher will have a better chance of getting a job.

How does coding work?

All code tells a machine to perform a specific task. Every time you use the Internet, your device uses a binary code –– a sequence of “1” and “0” that tells your computer which switches to turn on or off. It is a reliable way to store data and process information.

This process works faster with high-level programming languages, such as Python, Java, and JavaScript. Each programming language serves a different purpose, but they all take code that reflects human speech and translate it into machine code or low-level language. Programmers and developers write instructions for computers using high-level programming languages.

What are the advantages of coding?

When bootcamps opened in 2011, only tech junkies learned to code. Now, industries outside of tech are recognizing the benefits of coding, and it’s even taught in elementary schools – from Alabama to Florida. Coding can teach important concepts applicable to a career in technology or an entirely different field.

Why learn to code?

Learning to Code provides the training needed for high paying tech jobs. The most common career paths after bootcamp are: junior web developer, junior web designer, or data analyst. Coding teaches problem-solving skills, critical thinking, creativity, and persistence. These skills also prepare you for jobs outside of tech, such as healthcare, finance, and marketing.

Careers where learning to code is useful

What types of encoders are there?

Front-end, back-end, and mobile developers all write code that performs different functions.

Front-end developers manage the layout and functionality of a website. They use front-end programming languages ​​- such as HTML, CSS, and JavaScript – to write code to design a website. Their responsibilities also include SEO optimization by improving a webpage’s load time and mobile performance.

Back-end developers work on server-side development. They write code for web applications that control a website. Without this code, you would not be able to log into a website such as LinkedIn or Facebook and create a user profile. Programming languages ​​such as Python, JavaScript, Java, and Ruby allow back-end developers to write code that allows browsers to communicate with databases.

Mobile developers learn programming languages ​​such as Java, C ++, C #, SQL, and Python. The specific language used depends on whether the developers are building apps for iOS or Android devices. Mobile developers often work with graphic designers and data scientists.

What are the most popular coding languages?


Scripting system applications

Efficient and portable, with built-in functions that combine high and low level languages

Does not support object oriented programming


General purpose programming language used for back-end development

Easy to learn and read, versatile and portable with extensive libraries

May be slower than C or C ++


Client-side and server-side programming language used to create interactive websites

Easy to learn and understand, powerful, popular and flexible programming language that works with other languages

As client-side script, users can view the code, which is a security threat


Web Application Creation, Web Development, Web Servers, Web Scraping, DevOps, and Automation

Widely used open source programming language with user-friendly syntax, fast development speed, and powerful community

Limits on customization and turnaround times

C ++

Popular in game development, but also used for operating systems, web applications, and browsers

Fast programming language with fast image processing and object oriented functionality

Security issues, relatively slow and complex programming language with obscure rules


HTML-embedded server-side scripting language that serves interactive websites such as e-commerce web pages

Versatile and easy to learn programming language with a large online community; compatible with various operating systems

Common open source security issues cannot support large applications and weak type causes bugs


Created by Microsoft, this object-oriented back-end programming language is used for game development, Windows applications, and website development.

Versatile and efficient programming language used for many types of software and application development; similar to C ++

This complex language takes a long time to learn and requires code compilation.

Low level vs high level

Programming languages ​​come in two forms: low-level languages ​​and high-level languages. Low level programming languages, or binary code, look like a sequence of “1” and “0”. Computers understand low-level programming code and can process it faster. However, programmers can learn and use high level programming languages ​​faster because it looks like a human language.

How to learn to code?

There are different ways people learn to code. Some are self-taught and others go to college or bootcamp. Each route has advantages and disadvantages.


Websites like Treehouse or GitHub offer the possibility of learning to code for less money than bootcamps. The websites also offer limited free lessons for a short time. Students can watch videos for free for a trial period to learn Python, front-end web development, full stack JavaScript, and UX design.

You can also learn to code for free with free tutorials on websites. This helps beginners acquire the necessary basics before signing up for an intensive full-time bootcamp.


You can also learn coding basics through your smartphone. The apps available through Codecademy and Mimo allow beginners to practice coding through videos and online exercises. Many applications can be downloaded for free.

Training camps

Coding bootcamps train both beginners and advanced students. Popular bootcamps – such as Flatiron School, Fullstack Academy, Bloc, and Thinkful – require intensive training. Bootcamps last for weeks or up to six months, and often students are required to study full time.

Bootcamps require a significant investment of time and money. However, bootcamps, unlike apps or websites, also offer career services. Some bootcamps even offer job guarantees.

How to start coding?

You can start learning to code by reading and studying coding. Podcasts, YouTube videos, apps, and websites can provide the foundation for learning to code. You will also need the necessary software to code.

How difficult is coding?

Learning to code takes persistence and a passion for technology. Mastering any new skill takes time and practice. Some programming languages ​​are more difficult to learn than others. But you can learn to code even if you don’t like math.

How much do coding work pay?

Computer programmers make a good living after dedicating time and gaining work experience. Junior developers, a common position occupied by inexperienced coders, earn an average annual salary of $ 53,803, according to PayScale. Computer programmers with 10 to 19 years of experience earn an average annual salary of $ 79,000.
