To advance in the field of software development, you need to equip yourself with the latest programming skills. It would require a sound understanding of the programming languages’ popularity, their usefulness, and the highest paying programming languages.


How do I know which Programming Language I should learn?

Don’t know where to begin? Worry not; we have researched so you don’t have to. Today, we will take a look at some of the most in-demand programming languages of 2021. We will be ranking these languages based on the following factors:

Time required to learn it

How much time does it take to grasp for beginners or even experienced developers?

Job market

What is the demand and how much can you make with a particular programming language in 2021?


This aspect matters a lot when it comes to personal development. You need to know how fast can you build an app with it. When working with SMEs or startups, they require developers to create web and mobile apps faster and in a shorter amount of time.

So let’s get into the meat and potatoes of today’s topic.


Top 5 Highest Paying Programming Languages in 2021




Now, you might ask “Is Java Outdated?” It is not!

It is one of the oldest and robust programming languages and still a favorite of many developers. It is an object-oriented language and is mostly used for Android app development. That’s a major reason why it is still used today.

Why is Java still popular? Well, many big companies are still using it, and loads of trading applications are being built with it. Java’s popularity is currently in a decline due to programming languages like Kotlin, which also helps in Android development. 

(Most loved, dreaded, and wanted programming languages – Stackoverflow)

Java, however, is still one of the highest paying programming languages and quite in demand in the market. According to Indeed, software development companies are keen to hire Java developers and pay them over $100,000 per year.




Swift iOS app development is quite popular these days. If you want to help iPhone users make the most out of their smartphones and make a good income while helping them, you should learn Swift.

Its popularity might not be increasing anymore but it is not declining either. This means that Swift is a very stable programming language and worth investing in. 

It is also quite user-friendly compared to let’s say Java. There are tons of resources available on YouTube to aid the learning process and it is fun to work with too. It is easy to learn because you can just make stuff and put it on an iOS device.

Now, you can work as a freelance Swift developer or score a full-time job too. You can earn up to $115,000 annually with it.




SQL or Sequel (some argue it is not actually a programming language), is a Structured Query Language. So what are the benefits of learning SQL? Well, no matter what programming language you are working with, if you wish to create awesome web and mobile applications, there is no escaping DATA.

When dealing with data, you’re pretty much won’t be able to do without SQL. It’s an essential tool when it comes to storing data. So is SQL good for big data? It definitely is – For example; when you like a comment or a post on Instagram, that interaction (like) is stored somewhere. Or, when you make a post on Instagram or Facebook, log out, and then log back into your account, the post is still there.

Guess what’s making all of that possible? Yes, it is SQL talking to the database. That is why this programming language/query language is a programming essential and a must-learn. Be it any type of web development, (backend or full-stack), you will have to learn it to manage data.

The average annual salary of SQL developers is over $90,000.




It is an incredible programming language and some even consider it to be the best. If you dream and aspire to make amazing websites or create winning web applications, you will need to learn JavsScript. It will be quite helpful when developing front-end, backend, or for full-stack development.

Javascript is an extremely popular language and if you check GitHub, there is always a new framework rolling out to support it. There are tons of amazing libraries coming out for JS as well.

For instance; you’ve got ReactAngular, and all sorts of trending craziness happening around it. And even if you exclude these trends, JavaScript is still amazing. Every browser out there supports & runs it. It is a must-have skill that you need in your software development arsenal and it is one of the highest paying programming languages too. You can earn anywhere from $90,000 to $113,000 as a JavaScript developer.




Python is the number one programming language in the world. According to Google Trends and PyPI popularity index too, Python is the most in-demand and definitely among the highest paying programming languages in the world.

What’s amazing about Python is that it is a general-purpose programming language and it is used for building a wide range of applications and it is also very powerful. Before we get into more details, let’s see who uses Python today? Google is built off of Python, YouTube is developed using Python. Quora, Dropbox, and Reddit are also using it. These are just a few of many other companies that use Python.

There are very useful frameworks & libraries for Python that support state-of-the-art data science applications but the real reason behind Python’s popularity today is its implementation in Artificial Intelligence (AI).

Self-driving carsself-checkout at Walmart, and a lot of automation and Machine Learning (ML) applications today are being managed via Python development. This has made this language even more relevant and skyrocketed its popularity.

The best thing, however, is its ease of learning compared to all the other languages and it is also very beginner-friendly. It also allows you to build complex applications with relative ease and quite fast too. With frameworks like Django & Flask, the web development process is also seamless.

Average Python developer salary in the US is around $78,000, which can go up to $122,000 for experienced developers.

Does it matter What Programming Language You use?

The choice you make off of the list of the highest paying programming languages matters. It is just like how and where you live matters. It defines you, everything around you, and what you find yourself doing when you grow up.

Similarly, the programming language you choose today will define your future career path.

For instance; if you start with Swift and spend a lot of time learning and developing apps with it, you are much more likely to become an iOS developer.

If you opt for Java, you are likely to end up developing Android applications. Similarly, focusing only on web development will make you an expert JavaScript developer, using Node.js and similar frameworks and spending time on gaining expertise as a Data Analyst will polish your skills as an SQL developer.

However, if you want to ride the wave of the latest technologies such as AI & ML and make smart apps, you should spend more time polishing your Python development skills. It is easy to learn, one of the highest paying programming languages in the world, flexible, and also assists speedy app development.

So, there you have it, our top 5 programming languages that are guaranteed to secure your future without a university degree, provided you have the zeal and persistence to learn.
