What is Computer Programming?

I’m not the government. And I want more coders. Yeah. I want better doctors, nurses, lawyers and things too. But personally I want more coders. I just want everyone to have a basic understanding of how their computers work. Learning to code is important. It’s important to know how the technology around you works. Which drive my attention to write something like this to enlighten beginners or unskilled person to choose coding in tech industry.

What is Computer Programming?

On Wikipedia, the definition of “Computer Programming” is:

“Computer programming is the process of designing and building an executable computer program to accomplish a specific computing result.”

But what does that mean?

A computer itself isn’t smart. Yes they’re powerful and have the potential to carry out tasks much faster than a human. But computers need a human to write instructions and tell them what to do.

What exactly is a programming language?

Programming languages fall both within the spectrum of low-level languages, such as assembly, and high level programming languages, such as JavaScript.

What are the main programming languages used today? How many are there?

There seems to be some debate on the total number of programming languages on the internet. Wikipedia list approximately 700 of “all notable” current and historical programming languages.

Why are there so many programming languages?

Different programming languages are developed to satisfy different needs. This is demonstrated throughout the history of programming languages. There was the rise of general purpose programming languages from the 1970s onwards, such as C, C++, C#, Java, JavaScript, Go from Google, PHP,  Python, Ruby, SQL, TypeScript, etc.

Compiled vs. interpreted programming languages

As you start to become more familiar with programming languages, you will come across compiled and interpreted programming languages. What is the difference?

What is a compiled language?

Programming languages such as C, C++, and Java have a “build” process where your code is compiled down to a more readable format (machine language) for the computer.

What is an interpreted language?

JavaScript, PHP, and Python are examples of interpreted programming languages. There’s no build process and the code doesn’t need to be compiled. Your code is being interpreted or read line by line as you run the program.

Therefore, interpreted languages are slower than compiled languages. They have to be translated on the fly so the computer can understand.

But with just-in-time (JIT) compilers, interpreted languages are becoming faster and more efficient.

Which programming language(s) should I choose to learn?

Programming languages pretty much do the same thing, but they are just different ways of expressing the same instructions to a computer. Once you’ve grasped the concepts and fundamentals of one programming language.

The programming language you should choose to learn first depends on a number of factors. For example, I wanted to be a web developer, so I chose JavaScript as my primary programming language. Other languages for the web you can learn are PHP and Larverl

If you want to become a data scientist, then Python might be an option. Python is considered one of the best data science tools to analyze big data

Python is a general purpose programming language, and is also useful to learn if you want to get into the field of Machine Learning and Artificial Intelligence. If you want to become a Software Engineer then Java, C#, C++ could be an option. Java is one of the most popular and in demand languages in the world. It’s a versatile language which can be used for developing small to large enterprise software.

Some computer programmers have a bachelor’s degree in computer science or a related subject; however, some are self-taught from other fields like social science field. Most programmers specialize in a few programming languages.

What Computer Programmers Do

Computer programmers write and test code that allows computer applications and programs to function. They may translate designs from software developers and engineers into workable code. They may also update or expand the code of existing programs or test programs for errors, finding and resolving faulty lines of code.

Where Can I Work as a Computer Programmer?

Job opportunities for computer programmers exist across economic sectors and geographic boundaries. Large organizations and companies employ these professionals, as do small startups. Computer programmers can also work as independent freelancers, taking jobs as they become available.

Coding runs the world as we know it, but the vast majority of people aren’t even aware of its existence, let alone what it even is. Before we start, I want you to try to answer “What is Coding?” for yourself: right-click somewhere inside your browser window, and select ‘View Page Source’. Scroll through the window that pops up and see if you recognize or understand anything.

As you may have expected, you were just viewing the code behind this webpage, or the document object model (DOM). That means, that you see the full markup of the page and if you have learned at least the basics HTML, CSS or JavaScript, it might be easier to spot some familiar tags and elements.

What is coding? let’s define coding as the basic act of writing – in a programming language – a script that a computer can understand. This script will tell the computer to behave in a certain way, to do a certain thing, and to, ultimately, perform the actions that you want it to – if your code is right.

Computers don’t understand human language and in order for us to see some results (like display a web page), we have to write it in a way that the computer would understand.

Why Should I Learn Coding?

Now that we have touched on the basics of coding, it’s time to take a look at a few of the reasons why you should think seriously about learning to code. Coding can have huge impacts on both your personal and your professional life.

What Types Of Coders Are There?

To fully understand the coding background, you need to know that there is a wide range of different types of coders out there. Each of them specializes in a different thing, and each of them is required to learn different languages and techniques that allow them to specialize in these things.

Although I have explained what is coding and three of the most common types of coders below, there are many, many more. Some of the other types not touched on include systems engineers, game developers, and AI programmers – among others.

Front-End Developer

Front-end developers are the people who build websites. They are responsible for the design, layout, and the way content appears on a webpage. This is done in several ways, but the most popular front-end languages are HTML, CSS, and JavaScript.

Back-End Developer

Although a front-end developer is responsible for the major design and interactivity features of a website, the back-end developer is the person who builds the web apps that the website runs on. Web apps are complex applications that are designed to do a certain thing and are built into a website’s underlying code. Some of the things that web apps built by back-end developers allow you to do include: Log in and out of a website once you have created an account. Connect with friends and build a user profile. Social sites like Facebook and Twitter are great examples of this sort of thing.

Mobile App Developer

Although you may think that this is pretty self-explanatory, it is still worth going over. Mobile app developers create apps for iOS and Android operating systems (surprise surprise!). Recent statistics suggest that the number of smartphone users in the world is nearing 2.5 billion, which is a huge number.

This means that there is a huge demand for mobile apps. Apps like Facebook, Snapchat, and Instagram have already taken the world by storm – who says that you can’t create something similar?

But, before you do that, you will need to learn what is coding and also learn a mobile programming language. If you would like to program iOS apps, you will need to learn either Objective-C or Swift. Both of these languages are used alongside the development tool Xcode.

If you want to learn web or mobile development, you will need to learn one of these languages. If any of them interest you, click on this form.
