Choosing Programming Languages to Learn

picking the best programming language for you is dependent on your goals visual with a computer icon

In order to select the best programming language for you, you need to have a goal in mind. As mentioned above, different languages serve different purposes and work more efficiently in solving various problems. Naturally, certain programming languages are more prevalent in a variety of job roles as well so it’s best to look into the languages that best fit your career path or desired job role. 

In most people’s experiences, the first language they learn is the hardest, but once you have the fundamentals and mindset for it the learning process becomes quicker. It’s important to remember that the ease, difficulty, and usefulness of a language are pretty subjective, so you may find that your experiences don’t reflect the journey that someone else had learning a particular language. See some of the best programming languages to learn and more details about those languages in the exhaustive list below. These languages were deemed “popular” by their job demand and overall use, depending on your goals the best language for you could be something different. 

The comprehensive programming languages list below covers each language’s origin, programming type, who uses it, what it’s best for and any special features. Find resources to help you learn the language under our resources section. Read on to find the language that best suits your needs.
