Starting something new can be daunting. Learning a skill or
mastering a new piece of hardware is tough. Even tougher if you
have no-one at hand to help. Conversely as the complexity of our
consumer technology increases, the size of the requisite instruction
manual decreases or in some cases it simply disappears. At
numerous times in our lives we have all been “beginners”, there
is no shame in that fact and rightly so. How many times have
you asked aloud, “What does this button do?”. “Why doesn’t that
work?”. “What do you mean it doesn’t do that?”. “HELP!”. At the
start of any new journey or adventure we are all beginners but
fortunately for you we are here to stand beside you at every stage.

Over this extensive series of titles we will be looking in great depth
at the latest consumer electronics, software, hobbies and trends out
of the box! We will guide you step-by-step through using all aspects
of the technology that you may have been previously apprehensive
at attempting. Let our expert guide help you build your technology
understanding and skills, taking you from a novice to a confident
and experienced user.

Over the page our journey begins. We would wish you luck but we’re
sure with our support you won’t need it.

So you want to start coding? It’s not going to be an easy
road, and there are many pitfalls along the way, but
learning to program is an amazing skill and one that will
stand you in good stead for the future.

One of the hardest steps in learning to code is the first:
which programming language to learn. Then, where do
you go to find the tools you need and what do all those
terms mean? Don’t worry, we’re here to help you on
your way.

In this section we look at what you need to take those
first tentative steps into the world of coding.

Choosing a
Programming
Language

It would be impossible to properly
explain every programming language in
a single book of this size. New languages
and ways in which to ‘talk’ to a computer
or device and set it instructions are being
invented almost daily; and with the
onset of quantum computing, even more
complex methods are being born. Here
is a list of the more common languages
along with their key features.

Choosing a Programming Language

SQL stands for Structured Query Language. SQL is a standard language
for accessing and manipulating databases. Although SQL is an ANSI
(American National Standards Institute) standard, there are different versions of
the SQL language. However, to be compliant, they all support at least the major
commands such as Select, Update and Delete in a similar manner.

SQL

JavaScript (often shortened to JS) is a lightweight,
interpreted, object-oriented language with first class
functions. JavaScript runs on the client side of the web, that can be used to design
or program how the web pages behave on the occurrence of an event. JavaScript is
an easy to learn and also powerful scripting language, widely used for controlling
web page behaviour.

JAVASCRIPT

Java is the foundation for virtually every type of networked
application and is the global standard for developing enterprise
software, web-based content, games and mobile apps. The two main components
of the Java platform are the Java Application Programming Interface (API) and the
Java Virtual Machine (JVM) that translates Java code into machine language.

JAVA

C# is an elegant object-oriented language that enables developers to
build a variety of secure and robust applications that run on the .NET
Framework. You can use C# to create Windows client applications, XML Web
services, client server applications, database applications and much more. The
curly-brace syntax of C# will be instantly recognisable to anyone familiar with C,
C++ or Java.

C#

Python is a widely used high level programming language used
for general purpose programming, created by Guido van
Rossum and first released in 1991. An interpreted language, Python has a design
philosophy that emphasises code readability and a syntax that allows programmers
to express concepts in fewer lines of code. This can make it easier for new
programmers to learn.

PYTHON

C++ (pronounced cee plus plus) is a general purpose programming
language. It has imperative, object-oriented and generic programming
features. It was designed with a bias toward system programming and embedded,
resource-constrained and large systems, with performance, efficiency and flexibility
of use as its design highlights.

C++

Ruby is a language of careful balance. Its creator, Yukihiro “Matz”
Matsumoto, blended parts of his favourite languages (Perl,
Smalltalk, Eiffel, Ada and Lisp) to form a new language. From its release in 1995,
Ruby has drawn devoted coders worldwide. Ruby is seen as a flexible language;
essential parts of Ruby can be removed or redefined, at will. Existing parts can be
added to.

RUBY

Perl is a general purpose programming language, used for a wide
range of tasks including system administration, web development,
network programming, GUI development and more. Its major features are that it’s
easy to use, supports both procedural and object-oriented (OO) programming, has
powerful built-in support for text processing and has one of the most impressive
collections of third-party modules.

PERL

Swift is a powerful and intuitive programming language for macOS,
iOS, watchOS and tvOS. Writing Swift code is interactive and fun;
the syntax is concise yet expressive and Swift includes modern features that
developers love. Swift code is safe by design, yet also produces software that runs
lightning fast. A coding tutorial app, Swift Playgrounds, is available on iPad.

Programming is one of the most valuable skills you can pick up these days,
particularly for your career prospects; and great just to test your brain and get to
create something cool too. When you’re new to coding, it can be hard to know where
to start and it’s easy to get sucked down paths that could waste a whole lot of your
time and money. If you’re just getting started on your coding journey, here are some
tips to set you off in the right direction.

Learning to Code –
Study Tips

CHOOSE YOUR LANGUAGE

It may sound obvious but
choosing the
right coding or
programming language to
start learning is important
if you want the creative
process to be successful. If
you need learn to code for a specific reason,
finding a job for example, then you obviously
need to learn the language that’s relevant. If
you simply want to learn coding, then picking
a language like Python, that is both powerful
and relatively easy to learn, can make success
more likely.

LEARN WHAT BEING A CODER MEANS

Take some time to look at the things coding languages are used for; so if you
are interested in web design, look at how JavaScript is being used on the sites
you use every day; if you are in to mobile apps, look into Java or Swift and see
how they make apps work. It can also be useful and encouraging to check out
what qualified coders can expect to get paid by looking at local job sites. We
are not saying that if you learn to code Python you are immediately going to
be offered a £70,000 a year job but it can help spur you on to study harder.

PUT THEORY INTO PRACTICE

If you are completely new to coding, learning any programming
language can seem like a huge task. Getting completely bogged
down in pages and pages of code examples and explanations
is not likely to make the learning process much fun. In our
experience it is often better to learn through practice, or to
choose a task you want to perform with code, and then work
backwards to learn how to complete that task. By learning small
chunks and repeating what you have already learned at differing
intervals is called Spaced Repetition.
