The most important skill to learn in today’s world is to know how to write a computer program. Today, computers have entered in almost every industry. Be it the autopilot in an aircraft or digital speedometer in your bike, computers in various forms surround us. Computers are extremely useful for an organization to scale up well. Gone are the days of pen and paper. Today, in order to store and access your information, you absolutely need computers.
The programming and developer communities are emerging at a rate faster than ever before. Various new programming languages are coming up that are suited for different categories of developers (beginners, intermediate, and experts) as well as for different use cases (web application, mobile applications, game development, distributed system, etc). Every beginner is puzzled with the question, "What programming language should I learn?" Let us take a look at best Programming Languages to learn in 2020 for a job and for future prospects:
Python undoubtedly tops the list. It is widely accepted as the best programming language to learn first. Python is fast, easy-to-use, and easy-to-deploy programming language that is being widely used to develop scalable web applications. YouTube, Instagram, Pinterest, SurveyMonkey are all built-in Python. Python provides excellent library support and has a large developer community. The programming language provides a great starting point for beginners. Talking about those who are looking for a better job, you should definitely learn Python ASAP! A lot of startups are using Python as their primary backend stack and so, this opens up a huge opportunity for full-stack Python developers.

Java is another popular choice in large organizations and it has remained so for decades. Java is widely used for building enterprise-scale web applications. Java is known to be extremely stable and so, many large enterprises have adopted it. If you are looking for a development based job at a large organization, Java is the language that you should learn. Java is also widely used in Android App Development. Almost any business today needs an Android Application owing to the fact that there are billions of Android users today. This opens up a huge opportunity for Java developers given the fact that Google has created an excellent Java-based Android development framework - Android Studio.
C/C++ is like the bread and butter of programming. Almost all low-level systems such as operating systems, file systems, etc are written in C/C++. If you wish to be a system-level programmer, C/C++ is the language you should learn. C++ is also widely used by competitive programmers owing to the fact that it is extremely fast and stable. C++ also provides something called STL - Standard Template Library. STL is a pool of ready-to-use libraries for various data structures, arithmetic operations, and algorithms. The library support and speed of the language make it a popular choice in the High-frequency trading community as well.
Go, also known as Golang, is a programming language built by Google. Go provides excellent support for multithreading and so, it is being used by a lot of companies that rely heavily on distributed systems. Go is widely used in startups in Silicon Valley. However, it is yet to be adopted by Indian companies/startups. Those who wish to join a Valley-based startup specializing in core systems should master Golang.
R programming language is one of the most commonly used programming languages for Data Analysis and Machine Learning. R provides an excellent framework and built-in libraries to develop powerful Machine Learning algorithms. R is also used for general statistical computing as well as graphics. R has been well adopted by enterprises. Those who wish to join “Analytics” team of a large organization should definitely learn R.
Swift is the programming language that is used to develop iOS applications. iOS-based devices are becoming increasingly popular. Apple iPhone, for instance, has captured a significant market share and is giving a tough competition to Android. Therefore, those who want to serve this community can learn Swift programming.

Well… there were a few well-thought reasons behind this decision.
Python is a great language. I love it! It’s free of clutter and is simple to use. It also has better support for OOP features. So, why didn’t I choose Python? Because based on my research, Python is often used among people in the data science community, rather than professional software engineers.
Yes, you we use Python to build desktop and mobile apps as well as backends. However, Python is not the language of choice for building mobile or desktop apps. These days, the majority of people are building mobile apps using cross-platform solutions such as React Native or Flutter. Others do native development in Java (for Android) or Swift (for iOS). The same applies to building desktop applications with Python. Python is not very well known for that reason.Why not C#?
C# and Java are very similar in terms of syntax and they both have great support for OOP features. So, why didn’t I choose C# given that I have several C# courses?
Well… I looked at different sources to see the popularity of Java vs C#. Google Trends is a great resource. As you saw earlier in the post, Java is way more popular than C#. Does it mean it’s a better language? Well, it depends on _how _we define “better”.
What is better? A Ferrari or a truck? It depends on what you want to do. Ferrari is a super-fast car but it’s useless if you want to use it to move house. Programming languages are the same. There is no such thing as the best programming language. Every language has pros and cons. C++ is well known for its speed. Python is popular for its simple and clean syntax as well as tons of resources for machine learning.
Just because Java is more popular, it doesn’t mean it’s a better language than C#. In my opinion, C# is a more feature-rich language but Java was marketed better.
C# and Java have been rivals since day one. Many of the features we’ve had in C# for a long time were introduced in Java years later. Some features don’t exist to this day! For example, in Java, we don’t have optional parameters which are very handy. We have to overload a method. Ugly! Jave interfaces are also bad.
I personally prefer C#. But as I said, Java has had better marketing and that’s why it’s always been more popular than C#.Why Java?
So, I chose Java because it’s used more widely than C# amongst professional software engineers. There are more Java developers out there than C# developers. Most universities and colleges also tend to teach Java, rather than C#.
Now, all that aside, C# and Java are very similar in terms of the syntax. Recently I posted this tweet asking my students if this is Java or C# code?
The reality is I wrote this code in IntelliJ (a popular Java IDE). But the code is valid C# and Java code. Someone argued that this is an over-simplified example and shouldn’t be used as a basis for comparison. That is true. But my whole point is that if you understand this code, you can perfectly take my Data Structures or Design Patterns courses.What You Should Take Away
In my opinion, Java in the programming world, is like the English language in the world we live in. If Italian or Hindi is the only language you speak, you’re probably not gonna get very far ahead.
If you understand English, you have access to tons of valuable resources. Whether you want to learn programming, or painting, or piano, if you “understand” English, you have tons of resources in front of you. You don’t need to be fluent in speaking English. All you need is to just understand it.
