Other computer programming languages worth mentioning
As coders are innovative to solve different issues they work hard to develop new programming languages. This is why our top 10 list of the best programming language will never be final. There are two must know languages and one aspiring language that we’d like to mention next. Let us add them to our list as numbers 11 to 13.
Kotlin was developed in 2011 by JetBrains and fully documented on GitHub. It is a general-purpose and cross-platform language. Designed to interoperate with Java and JVM. Kotlin is widely used for native iOS apps sharing business logic with Android apps. Furthermore, Kotlin is the preferred programming language of Android app developers.
12. HTML & CSS
HTML (Hypertext Markup Language) is the basic programming language for website developers. Some people would say that HTML and CSS are not real programming languages. It is important to understand that HTML and CSS are quite different than others. Both are considered declarative languages. In simple words, HTML and CSS are basic statements declaring what should exist on a web page. Other coding languages are computational and that’s what makes these two different. So if you are an absolute beginner, then you should first learn basic HTML and CSS coding.
Ruby is a high-level interpreted language for general-purpose programming. Don’t get confused about Ruby and Ruby on Rails which are two completely different subjects. Ruby was influenced by Perl, Ada, Lisp, and other languages. Ruby became very popular when Airbnb was introduced. Airbnb uses Ruby as its main programming language for its booking website.
The world of computer science has given birth to a whole new crop of unique programming languages suitable for various use cases. From software development to iOS or Android app creation, there is a language that is suitable. For anyone willing to start off on learning a programming language, there are key criteria to take note of before pitching their tents. Some of these criteria include technical qualities, learning curve, demand and popularity, benefits, and downsides, amongst others.
Beyond these, the choice of the right programming language should be backed by your underlying goals. If you want to be a web developer, Python, PHP, and C# amongst others may be right for you. If your goal is to be a data analyst, you may want to look into R and Python. Let your goal influence your choice of programming language to embrace.
