How to Code: A Beginner’s Guide

What Is Coding?

'Code' is a term for the programming language that tells a computer what to do and 'coding' is writing it.

Computers do not understand English (or any other human language), and coders create a translation between human-understandable and computer-understandable instructions.

Every computer, smart phone, laptop or connected device works using a programming language that has been coded to make it operate in the correct way.

While programming and coding are defined as separate skills – a coder creates a script that the computer can understand, while a programmer puts the code together to make a program run – in practice they are interchangeable:

to make the computer work in the correct way, a coder or programmer needs to create the instructions for the computer’s actions through code in a script.

An important facet of the script that is used is syntax.

As in human language, the syntax of the script includes the rules of structure and form rather than any logical meaning. Think of syntax like grammar – words go in a specific order because those are the structural rules, not because it is logical.

The syntax is incredibly important in programming languages – the wrong syntax would make the entire script unusable.

Key Coding Terminology

Programming language, like any other language, comes with unfamiliar terms that need to be understood:

Hardware

Hardware refers to the physical components of a computer, from the screen, keyboard and mouse to the internal parts like the graphics card and the CPU (Central Processing Unit).

Software

Software is a term for the collection of instructions and data that tells the computer how to work and complete the activity that is needed.

The programs you run on your computer or phone are software.

Binary Numbers

Binary numbers are an essential part of the way computers read and interpret information.

Computers can only count to 1. A series of 1’s and 0’s that are known as ‘bits’ make up the binary number system.

Scripts

A script is a series of steps that are written for a computer to follow.

The computer processes the script from top to bottom, reading and executing each statement in order.

Statement

A coding statement is a series of words, numbers and punctuation that is put together to tell a computer to perform an action.

Scripts are made of multiple statements.

Algorithm

An algorithm is a set of instructions that the computer follows in order to solve a problem (such as which posts to display at the top of your social media feed) – it is essentially the thought process of the computer.

Argument

When creating a code, the function of the code can be amended using an argument that provides more information (such as a variable).

Variable

Often a single word or number used throughout the code. It can be a string (a word or a phrase), a single character, or even a representation of true and false (these are called Boolean).

Source Code

Source codes are essentially snippets of statements that have a specific purpose.

These can then be assembled into a computer program that performs executable actions.

What Are Programming Languages?

There are possibly thousands of human languages, and there may be just as many programming languages.

Many have been designed for a specific use – that is, proprietary languages that are created for a particular purpose.

However, there are quite a few programming languages that are widespread and most of them are simple for beginners to learn. These programming languages can be used to make the front and back-end of websites, apps, games and other computer programs.

Types of Programming Languages

Here are just a few of the many programmung languages out there:

HTML

HTML (Hypertext Markup Language) is possibly the most widespread coding language and is heavily featured in front-end internet development.

It is a popular choice for beginner coders because the language is simple to learn, and the syntax is straightforward – and it can be used to create websites without too much in-depth knowledge.

CSS

CSS (Cascading Style Sheets) is another language used for front-end development and is often learned in conjunction with HTML as they work well together for the style and design of the finished product.

It is reasonably simple to learn and makes the most sense when used with HTML.

Java

Java is a very versatile coding language, used throughout back-end web development and also in mobile app creation.

Although it is quite simplistic, it is favoured by developers because it is easy to learn and use, thanks to the syntax (which is similar to English).

It is also scalable, which means that the scripts can grow with the programming needs.

Python

Python has become a well-known coding language because it is everywhere.

It is versatile enough to use for all programming applications and is now the most common coding language taught in schools (and through online learning portals), with many software and programming roles demanding a solid grasp of Python.

JavaScript

Despite the similar names, Javascript is not the same as Java.

JavaScript is the coding language that is used in front-end website development to create more interactive interfaces like videos, animations and even GIFs.

JavaScript can also be used in back-end development and is one of the fastest growing coding languages.

What Is Coding Used For?

Coding can be fun – and it is always good to have a challenge.

Further, learning coding could be a valuable upgrade to your skill set that could lead to a lucrative new career.

Many people have basic ICT skills but fewer people can code.

Working with code could offer job security, a pay rise, better work/life balance and a number of (sometimes surprising) roles both in and out of the IT and tech industry.

Read on to find out about some of them.

With 6+ years of experience, a coder or developer earns an average salary of £45k plus in the UK.

Coding Job Titles

Junior/Senior Developers

Developers write scripts, work with databases, create complex applications and complete user analysis.

Mobile App Developers

The fast-growing market for mobile app development, covering everything from high-end games to receipt trackers, means that coders who can produce interesting and useful applications for iPhone and Android are always in high demand.

Programmer

Taking the plans of developers and combining them with the creativity of the designers is where programmers and coders shine.

Creating a useable code and programs that execute exactly the processes needed takes extensive knowledge.

Data Engineer

Coding can be used to produce data that is necessary for businesses to succeed.

Data engineers build, maintain and test solutions as well as create large-scale processing systems.

Data Scientist

Taking the data created and parsed by data engineers, data scientists analyse information to uncover important insights that are useful to the success of a business.

Designer

Design that uses digital tools is the modern answer to pencil and paper, and knowledge of coding can make the manipulation of designs simple.

Designers are important for everything from website layout to logo creation, video production and game design.

User Experience (UX)

UX designers are an essential part of online and offline businesses – and coding knowledge and experience can help those involved make sure the users experience the absolute best of the business.

Start-Ups

Entrepreneurs and start-up businesses often have limited budgets but lofty ideas – and if you want to be involved in an exciting new business, having knowledge of code makes you a valuable commodity – even more if it is your business idea because then you will not need to hire someone.

Freelance Coder

Being self-employed and running your own business can be difficult – but if you have the skills to build websites, design e-commerce sites and design your own marketing and branding, you can be your own tech guru, saving time and money.

Plus, other people often want to hire someone with such skills on a short-term basis, which works well for freelancers.

Why Is It a Good Idea to Learn to Code?

Learning to code has so many benefits – aside from the obvious one of developing a new skill set, of course.

Increased Income (Often for Fewer Hours)

Having the coding skills that lead to a new role could mean better pay without stretching yourself in terms of hours.

Being a great programmer or coder could lead to roles in tech firms, start-ups and elsewhere – with the added bonus that you can effectively choose your hours and your pay from the ranges on offer.

Job Security

Technological development is not slowing down. Everything from virtual reality and artificial intelligence to the increasing prevalence of mobile technology relies on coding, so this is an area of continuing growth.

Coding is a valuable skill and, alongside lifetime learning, it is always going to be in demand – competent coders will have increased job security for the future or beyond.

Become More Employable – Even Outside of Coding

Having skills over and above those required for a job role can make you stand out when job hunting.

For recruiters, you would stand out over and above all the other candidates if you can offer coding skills.

You Can Develop Your Own Programs or Work for Yourself

Becoming skilled in coding means you can start developing your own programs and work for yourself, building up your own ideas and projects and not solely other people’s.

Whether you choose to work on open-source code or create something new and amazing, there are several options that you can take to work for yourself with your newfound coding skills.

Industry of Continuous Learning

Every day in the coding world, you are learning – the whole industry is about developing.

Whether it is programming languages, working in artificial intelligence (AI) or in a brand-new area, learning coding is a journey that does not end after a simple course.

More Free Time and a Better Work/Life Balance

Being able to choose your hours, whether as an employee with a lot of offers to pick from or through freelance work, helps you gain a better balance between working and free time.

Investing the necessary time now to learn the skills that you need for the future could see you working less.

Coders and programmers can often work from home, meaning that the time they would have spent commuting can now be spent relaxing.

You can learn to code through various means – you can start on your own, learn from others or take official courses.

Whichever way you choose to learn, there are many resources available that can help.

Here are some steps to get you started and help you choose which method is right for you:

Final Thoughts

Coding can be learned on your own through various online resources like YouTube and books – but if you prefer to follow a structured plan for your learning then there are many courses available online that will help, both free and paid.

Reskilling or upskilling in the tech industry, especially in a new coding language, could offer more salary, better hours or the opportunity to freelance – as well as job security due to the skill’s desirability.

All your practice can be consolidated in many ways, from writing your own projects through dissecting someone else’s code to playing games.
