There are hundreds of different programming languages out there. As a newcomer you can ignore the fact that most of them exist. However, even if we narrow the list to just a dozen mainstream languages, deciding on what programming language to learn first can be a daunting task. You might find yourself asking, should I learn C, C++, Java, C#, or PHP first? If you ask ten programmers this question, you’ll probably hear ten different answers. Here is my take.
Much as with human languages, programming languages are used to communicate. Interestingly they still involve communication between people, whether other programmers will end up reading/modifying/enhancing your code or you’ll do at a later point in time. Unlike natural languages however, programming languages are unequivocally understood by computers, thanks to the aid of interpreters, compilers, and similar types of software.
Depending on the kind of program you’re trying to write, and in which environment you’re working, you’ll find that some programming languages are better suited than others for certain tasks, even if most common programming languages are labelled as being “general purpose”.
This is a profession where most of your skills are developed and honed by actually “doing”. If you grasp the fundamentals of programming outright, you can easily pick up a specific language and framework when you need to build iPad applications or whatever else you’d like to create.
A well-rounded programmer will end up learning several programming languages and tools over the course of their career. That said, if you are just starting out, focus on one language first. While this might seem a tad dull on the surface, the good news is that unless you pick a truly exotic programming language, a lot of what you learn will be applicable to other programming languages as well. Remember that at this stage, above all else, you are learning how to communicate your thoughts in precise statements for other programmers to understand (and for the computer to execute).
For this reason, you can’t really go too wrong with any of the “somewhat mainstream”, general purpose programming languages (e.g., C, Java, C#, Perl, Ruby, Python, or Scheme). That said, particularly if you are learning on your own, I’d advise that you go with a language that will make your learning trek easier. In other words, opt for a programming language that is widely used, well documented, and beginner-friendly. You’re looking for one that isn’t overly bureaucratic, doesn’t require you to manage memory directly, or have a deep understanding of mathematics to get started.
As such, my suggestion would be to start with Python, and use it as a tool to learn the general craft of programming. Learning Python is fun, easy, and useful. You’ll be able to use it for a wide array of projects in several environments (scripting, web, scientific research, etc…).
Once you have learned the fundamentals of programming, have a decent command of the Python language, and have gained some experience with practical Python projects, you should be better armed to evaluate and pick up other languages and frameworks based on the projects you intend to develop or contribute to in the future (Open Source projects are awesome for this purpose).
