“A language that doesn’t affect the way you think about programming is not worth knowing.” 
                                                                           ― Alan J. Perlis

What is a programming language:

Wikipedia defines a programming language as, “A programming language is a formal language, which comprises a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement algorithms.”

For beginners just stepping in the world of programming, the biggest dilemma is to decide where to start from or which language to opt for first in order to make your career grow as a programmer in 2020. At times, even professional coders face situations where learning a new language seems to be more fruitful.

Choosing which programming language to learn involves a number of points to keep in mind. You will need to find a balance between the time and effort involved in learning any language and the perceived benefits of the language.

Which programming language is the best? -is an example of the wrong statement of the question.

Instead, you should be asking:

Which programming language is the most suitable for …

Which programming languages are used for …

So we are in December of 2019 and as the year is about to end, here’s a list of what programming languages will be in demand in 2020.

One of the easiest ways to pick the best programming languages to learn in 2020 is to study the market trend and work accordingly. However, I will make your task a bit easier as I have compiled a list of the top 10 in-demand programming languages of 2020. So, let’s get straight into this. Here is how the list goes:

Top Programming Languages To Learn In 2020:

1. JavaScript:

Is it worth learning JavaScript

JavaScript is one of the most powerful programming languages out there. It is impossible to be a software developer nowadays without the usage of JavaScript in some way. It is one of the best programming languages to learn in 2020. According to the Stack Overflow’s 2018 Developer Survey, 71.5% of professional developers ranked JavaScript as the most popular programming language for the sixth year in a row.

People often ask which programming language is best for web development? Well, if we go by the stats the answer is unsurprisingly JavaScript.

JavaScript is everywhere. It’s vital to both front-end and to back-end developers.

Uses of JavaScript

Pros:

  • Speed: Being client-side, JavaScript is very fast because any code functions can be run immediately instead of having to contact the server and wait for an answer.
  • Simplicity: JavaScript is relatively simple to learn and implement.
  • Versatility: JavaScript plays nicely with other languages and can be used in a huge variety of applications. Unlike PHP or SSI scripts, JavaScript can be inserted into any web page regardless of the file extension. JavaScript can also be used inside scripts written in other languages such as Perl and PHP.
  • Server Load: Being a client-side reduces the demand on the website server.

Cons:

  • Security: Since the code executes on the users’ computer, in some cases it can be exploited for malicious purposes. This is one reason some people choose to disable JavaScript.
  • Reliance on End User: JavaScript is sometimes interpreted differently by different browsers. Whereas server-side scripts will always produce the same output, client-side scripts can be a little unpredictable. Don’t be overly concerned by this though – as long as you test your script in all the major browsers you should be safe.

2. Python:

Python Logo

Python is one of the general-purpose, user-friendly and one of the most versatile programming languages to know. Python has seen a significant rise in the index and deemed as one of the most popular programming languages in recent years due to the wide variety of libraries it offers.

According to Stack Overflow, there is one section which says “To be adopted or migrated to be—or to migrate too soon”, and for python, it’s 12% which is the highest for any programming language. People who have migrated to Python are close to around 42%, and therefore in my list of most in-demand programming languages in 2020 is Python.

Python is being used by many for various purposes now some of which are Software Engineer, Software Developer,  Web Developer, Quality Assurance Engineer, Data Science.

Where is Python programming language used

Pros:

  • Python is easy to learn for even a novice developer. Its code is easy to read and you can do a lot of things just by looking at it. Also, you can execute a lot of complex functionalities with ease, thanks to the standard library.
  • Supports multiple systems and platforms.
  • Object-Oriented Programming-driven.
  • With the introduction of Raspberry Pi, a card-sized microcomputer, Python has expanded its reach to unprecedented heights. Developers can now build cameras, radios and games with ease. So, learning Python could open new avenues for you to create some out-of-the-box gadgets.
  • Python has a plethora of frameworks that make web programming very flexible.
  • Gives rise to quick development by using less code. Even a small team can handle Python effectively.
  • Allows scaling even the most complex applications with ease.
  • A large number of resources are available for Python.

Cons:

  • Python is slow
  • Python is not a very good language for mobile development.
  • Python is not a good choice for memory-intensive tasks.
  • It’s near impossible to build a high-graphic 3D game using Python.
  • Has limitations with database access.
  • Python is not good for multi-processor/multi-core work.

3. Java:

Java for Android Development

Java undoubtedly makes it to the list of top programming languages to learn, be it any year. According to Stack Overflow’s 2018 survey, 45.5% of professional developers favor. There’s a great saying ”write once run everywhere” capture one of the keys that make Java so valuable, the reason for Java’s enduring appeal being the Java Virtual Machine (JVM) which makes it cross-platform compatible. It is still one of the best coding languages to learn.

Java is also the soul for Android development and the most common language for developing Android apps. The language is favored by enterprises too, with roughly 90 percent of Fortune 500 companies using Java for building applications and other back end systems.

is it worth learning Java

Pros:

  • Object-Oriented language.
  • Java offers APIs for different activities like Database connection, networking, XML parsing, utilities, etc.
  • Powerful open-source Rapid Development tools and libraries are available.

Cons:

  • Memory management in Java is quite expensive.
  • The absence of templates can limit you to create high-quality data structures.

4. Swift:

best programming languages to make money

Next on the list is Swift. Swift was developed by Apple in July 2010 so as to make it easy for iOS developers, replacing Objective-C. Developers use Swift to build powerful, high-performance, native iOS, macOS and Linux apps. It is one of the most used programming languages for iPhone application development because of its immersive ability to employ compilers and syntaxes based on different C-based languages.

C++ is a programming language that was developed by Bjarne Stroustrup in 1983. C++ is a more modern, object-oriented version of C.  C++ still remains in demand owing to its flexibility, performance and multiple contexts where you can use it. A career in C++ would usually involve the development of desktop applications that are focused on performance-intensive tasks.

C++ or Java

Pros:

  • It is a popular language, and thus, there are many compilers and libraries
  • Other programming languages like C, C#, and Java have very similar syntax to C++, make it easy to learn for everyone who knows C++.
  • No garbage collector is running in the background.

Cons:

  • The syntax is complex, and the standard library is small, making this language very difficult to learn for the beginner programmer.
  • C++ program can’t support garbage collection or Dynamic Memory Allocation
  • The object orientation system in C++ is unnecessarily basic compared to other languages.

  1. Aside from your Rust list having some very excellent sounding Cons, I don’t think I’ve ever seen a list of Rust’s Pros that didn’t mention the most unique thing about the language (compile guaranteed safety, no GC, no added runtime overhead). Also is the only language I know that can prevent code with data races from compiling.
