I often get asked by beginner programmers what programming language they should learn.
This, of course, is a tough question to answer. There are so many different programming languages today that a new developer, or even a seasoned developer, wishing to retool his or her career, could learn.
I’ve actually tried to answer this question before in a YouTube video, but I want to revise and refine my answer a bit here, because some of my views have changed and I’d like to give a bit more detail as well.
The wrong question to begin with
It turns out that what programming language you choose to learn is not actually all that important
Things have changed quite a bit from back when I first started my career in software development. Back when I first started out, there were much fewer choices of programming languages and there were much fewer resources available for reference. As a result, the choice was much more important.
For example, I started out learning C and then C++. At that time, it took quite a bit of work to master the language itself and to understand all of the standard libraries that were available. A good C or C++ programmer back then had a very in-depth understanding of every nook and cranny of the language and they needed this knowledge, because of two main reasons.
- References were not as widely available, so figuring out a syntax or library available involved flipping through a huge book, rather than just typing some keywords into Google.
- Programming, in general, was done at a much lower level. There were far fewer libraries available to be able to work at higher levels, so we spent more time working with the language itself and less time working with APIs.
Contrast that with the programming environment of today, where not only is information widely available and can be accessed with ease, but also there are a large number of programming languages that we effectively use to program at a much higher level due to the vast amount of libraries and reusable components available to us today.
In today’s programming environment, you tend to not need to dive as deeply into a language to be effective with it. Sure, you can still become an expert in a particular programming language, and it is good to have some amount of depth in at least one language, but you can literally learn a new language in less than a week and be effective with it almost immediately.
Now, before your alarm bells go off and you write me off as crazy, let me explain that last sentence in a bit more detail.
What do you mean you can learn a programming language in a week?
What I mean by this is that once you understand the basic programming constructs available in just about all programming languages, things like conditionals, loops and how to use variables and methods, you can take that same knowledge to a different programming language and just learn how to do those same things in that language’s syntax. In fact, most IDEs today will even help you with the syntax part, making your job even easier.
If you are already fluent in multiple programming languages, you probably agree with what I am saying, but if you have only ever learned one programming language or none at all and are looking to learn your first programming language, you might be a little skeptical. But, take it from someone who has learned and taught programming languages which I have learned in a week, the basics are pretty much the same.
Check out this book which basically deals with this exact subject, Seven Languages in Seven Weeks: A Pragmatic Guide to Learning Programming Languages.
Now, if you are just starting out, it is pretty unlikely you’ll be able to learn a whole programming language in a week. This brings us to the question, you may be asking yourself…
So, what programming language should I learn then?
Hold up. I’m still not quite going to answer that question. Because, it still isn’t quite the right question.
Instead of getting hung up on what programming language you want to learn, you should instead ponder what you want to do.
Learning by doing is the most effective way to learn, especially if you are doing something you have an interest in or is fun to you.
So, I always start new want-to-be developer out by asking them what they want to build.
Do you want to build an Android application? How about an iOS application? A web page? A game?
First, figure out the answer to this question and then let that answer guide you to choose the technology and programming language you will use to achieve that goal.
Don’t worry so much about which programming language or technology is most valuable. You can’t make a wrong decision and regret it later, because it won’t take you much time to retool later if you need to. Once you have the basics down and have actually used a programming language to build something, you’ll find that doing it again will be much easier.
I like to encourage new developers to write a mobile application—especially an Android application.
Here are some reasons why:
- A complete Android application can be built by a single person. Creating a complete application will really help you to feel confident about software development and is one of the best ways to really learn to code. I spent a good deal of my early career only being able to create bits and pieces of things, and it was frustrating, because I never knew if I could really “code.”
- By learning Android, you learn Java and how to use libraries and APIs. This will give you a good programming language to start with and you’ll get some valuable experience with APIs.
- Google gives you some free help and makes things pretty easy to learn. Since Google really wants you to create Android applications, they have put quite a bit of work into creating easy to use tools and tutorials to help you be successful quickly. (I’ve also created some tutorials, which you can watch at Pluralsight here as well.)
- You can actually make money while learning and teach yourself a very valuable and upcoming skillset. Not only can you sell your Android application or monetize it in some other way, but you will be learning a complete set of software development skills for a platform that is in very high demand.
Aha! So Java it is then?
No, not exactly.
