How to Choose a Programming Language to Learn

Choosing a programming language to learn may seem like a daunting task, especially since there are a lot of options available. Ultimately, it depends on your career goals and objectives. Some of the things you can consider before making a decision are the language model, syntax, and community. Read below for tips on how to choose a programming language.

Know Your Models

There are two distinct coding language models. The first is structured programming, an older and more straightforward model. Commands execute in a step-by-step fashion in the order in which they are written. It utilizes directional commands to navigate the code and is full of loops and subroutines designed to execute under specific circumstances. 

Object oriented languages, by comparison, establish containers and objects. Programs written in object oriented languages, such as Java or C++, don’t have a directional flow and they move from object to object as needed. Familiarity with basic models can give you an idea of which programming language you would be able to learn more effectively. 

Learn Your Syntax

Computer languages have particular syntax designed for their particular needs, but most of them follow standard design principles. The syntax provides each language with the rules and symbol definitions needed to establish meaning and create functioning programs. When a program contains syntax errors, it will not perform its functions correctly.

Some languages like Python, for example, are known to be beginner-friendly due to their English-like syntax. This makes it easier for any English-speaking programmer to understand its structure and syntax, regardless of how new they are to coding. The code is also less verbose and simpler to write, read, edit, and maintain.

Seek a Coding Community

All coding languages have a community built around them. Naturally, more popular languages like JavaScript and Python will have a bigger community of developers. According to SlashData’s latest State of the Developer Nation report, JavaScript has 17.4 million active developers, followed by Python at 15.7 million active users. 

People that are new to JavaScript or Python also have access to additional support, learning opportunities, and resources. Should they face any issue while learning, they can easily find the answer to their question by reaching out to the developers’ community or looking up similar problems on public forums. Chances are, someone has faced the same challenge before. 

Know What You Want to Code

Above all, it is recommended that you decide which language to learn after determining the type of projects you would like to work on. Keep in mind the answer to these questions: Are you learning to code to unlock new career opportunities? Are you a career-changer looking to break into tech? Are you interested in expanding your technical skills? Or are you learning just for fun? 

For example, if you are learning to code to get into web development, higher-level languages like JavaScript would be a better fit for you. On the other hand, if you want to work with embedded systems, a language with manual memory management like C would be a good idea instead. Research your field of interest, career goals, and hiring trends before deciding.   

Which Programming Language Should I Learn First?

Deciding which programming language to learn can be intimidating, especially if you are a complete beginner. The good news is that there really is no wrong decision. Some languages may be favored among experienced developers but they may not suit your intended use. As mentioned, the best programming language to learn is the one that checks all of your boxes. 

The most important step before making a final decision is to verify which language will align best with your future projects. Do you want to build data science apps? Maybe learning Python would be best. Do you want to build apps for iOS? Swift is a great language for that. Consider which language meets your goals and start coding.
