What is coding and what does it do? A Beginner’s Manual

Coding allows you to browse and interact with websites, like this one. But how exactly does coding work?

Writing instructions to communicate with machines is what software programming or computing programming entails. All gadgets rely on code to function, including laptops, desktops, phones, and tablets.

Cities are also run by code. Computers control traffic lights that have been designed to fulfill certain tasks. Even astronauts aboard the International Space Station must be able to code. Coding opens up numerous employment prospects in technology and other fields.

What exactly is coding?

what is coding and what does it do

Coding is the process of converting computer instructions into a format that a computer can comprehend. Every website and app exists because code is written by programmers. You do not, however, have to work in technology to use code. In fact, most coding careers can be found outside of the computer industry. What can you accomplish with coding?

Learning to code lays the groundwork for a variety of rewarding job choices. Bootcamp graduates may need to gather experience as junior developers before earning six-figure wages.

Your coding career will be determined by your work experience, education, and programming language knowledge. Coding trains you to become a web developer, game developer, computer network architect, or computer system analyst. According to the Bureau of Labor Statistics, computer information and technology occupations will rise at a 13% annual pace between 2020 and 2030.

Job growth, on the other hand, differs by occupation. Computer programmers, who earn a median annual income of $89,190, are expected to lose 10% of their jobs. Candidates with bachelor’s degrees or higher have a better probability of getting hired.

What is the process of coding?

All code instructs a machine to do something. When you connect to the Internet, your device employs binary code, which is a series of “1s” and “0s” that informs your computer which switches to turn on and off. This is a dependable method of storing and processing data.

This process is accelerated by high-level programming languages like Python, Java, and JavaScript. Each programming language serves a distinct purpose, but they all take code that is similar to human speech and convert it to machine code or a low-level language. Programmers and developers use high-level programming languages to create instructions for machines.

What are the advantages of coding?

When the first bootcamps began in 2011, only tech junkies learned to code. Coding is now taught in elementary schools from Alabama to Florida, and it is recognized by businesses other than technology. Coding can teach vital concepts that can be applied to a job in technology or a completely different industry.

Why learn to code?

Learning to code gives the necessary training for well-paying computer professions. Following bootcamp, the most popular employment paths are junior web developer, junior web designer, or data analyst. Coding promotes problem-solving abilities, critical thinking abilities, creativity, and perseverance. These abilities will also prepare you for positions in fields other than technology, such as healthcare, finance, and marketing.

What types of coders exist?

Front-end, back-end, and mobile developers all write code that serves various purposes.
Front-end developers are in charge of the layout and functionality of a website. They write code in front-end programming languages such as HTML, CSS, and JavaScript to build a website. Their tasks also include improving a webpage’s load time and mobile performance in order to optimize SEO.
Back-end developers are responsible for server-side development. They create code for web apps that are used to control a website. You couldn’t create a user profile on a website like LinkedIn or Facebook without this code.

Back-end developers can write code that allows browsers to interface with databases using programming languages such as Python, JavaScript, Java, and Ruby.
Programming languages for mobile developers include Java, C++, C#, SQL, and Python. The language utilized depends on whether developers are creating apps for iOS or Android devices. Mobile developers frequently collaborate with graphic designers and data scientists.

Name of language What is this language used for? Pros Cons
C Scripting system applications Efficient and portable, with built-in functions that combine high- and low-level languages Does not support object-oriented programming
Python General purpose programming language used for back-end development Easy to learn and read, versatile, and portable with vast libraries Can be slower than C or C++
JavaScript  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 a client-side script, users can view the code, which poses a security threat
Ruby Creating web applications, web development, web servers, web scraping, DevOps, and automation Widely used open-source programming language with a user-friendly syntax, a fast development speed, and powerful community Limits on customization and runtime lags
C++ Popular in game development, but also used for operating systems, web applications, and browsers Fast programming language with quick image processing and object-oriented features Security issues, relatively slow, complex programming language with obscure rules
PHP Server-side scripting language embedded in HTML that serves interactive websites such as e-commerce webpages Versatile, easy-to-learn programing language with a vast online community; compatible with various operating systems Common open-source security issues cannot support large applications and weak type causes bugs
C# Created by Microsoft, this back-end, object-oriented programming language is used for game development, Windows applications, and website development Versatile and efficient programming language used for many types of software and applications development; similar to C++ This complex language takes a long time to master and requires code to be compiled.

High-level vs. low-level

There are two types of programming languages: low-level languages and high-level languages. Low-level programming languages, often known as binary code, appear as a series of “1s” and “0s.” Computers can process low-level programming code faster because they comprehend it. However, because it looks like a human language, programmers can learn and utilize high-level programming languages faster.

How can you learn to code?

People learn to code in a variety of ways. Some learn on their own, while others attend college or bootcamp. Each route has benefits and drawbacks.


Websites like Treehouse and GitHub allow you to learn to code for less money than bootcamps. Websites also provide a limited number of free courses for a limited time. During a trial time, students can watch videos to learn Python, front-end web development, full-stack JavaScript, and UX design for free.

You may also learn to code for free by following free online tutorials. This allows newcomers to build the necessary foundation before enrolling in a full-time intense bootcamp.


You can also learn the fundamentals of coding using your smartphone. Codecademy and Mimo apps allow newcomers to practice coding through video and online exercises. Many apps are available for free download.


Coding bootcamps educate both novice and advanced pupils. Bootcamps like Flatiron School, Fullstack Academy, Bloc, and Thinkful demand extensive training. Bootcamps can last several weeks or up to six months, and students are frequently required to study full-time.

Bootcamps necessitate a significant time and financial investment. However, unlike applications or websites, bootcamps also provide career assistance. Some bootcamps even guarantee employment.

How do I get started coding?

You can start learning to code by reading and researching the subject. Podcasts, YouTube videos, applications, and webpages can help provide the groundwork for learning to code. You will also need the necessary software to code.

How difficult is it to code?

Learning to code necessitates perseverance and a love of technology. Any new skill takes time and effort to master. Some programming languages are more difficult to learn than others. Even if you dislike arithmetic, you can learn to code.

What do coding jobs pay?

After putting in the effort and gaining professional experience, computer programmers can earn a good income.
