In this blog, we’ve compiled a list of the 4 best programming languages to learn in 2022. We discuss how they’re used, and the pros and cons of each. We’ve even included an Easy to Difficulty rating scale and a Popularity scale to help you decide. You’re welcome!
4 Top Programming Languages to Learn
What is Python?
Python is a general-purpose programming language with a wide range of capabilities including web and software development, automation, and data analysis. What sets Python apart from most other programming languages is that its syntax uses elements from natural English. This makes it easy to read and learn by both developers and non-developers.
Being a ‘general purpose’ programming language Python is super versatile with a range of capabilities that aren’t restricted to a specific problem. This makes Python one of the most popular programming languages among coders. Almost anyone can use it! So, why learn Python? Read on.
What is Python used for?
Python has had multi-domain applications. Netflix’s recommendation engine that shows you film, and TV suggestions based on your viewing history was made with Python. Fun fact: Netflix spends a cool $1 billion annually on this tech! Also, the software that powers self-driving cars was made with Python.
Here are some applications for Python:
- Data Science
Python is perhaps most commonly used in data science applications. This includes everything from data visualisation – like pie charts, bar graphs and 3D plots – to data analysis. Python also has libraries like TensorFlow and Keras which allow you to write codes for data analysis programmes more quickly and efficiently.
Python can be used to automate a series of repetitive tasks like renaming files and sending scheduled emails or text messages. The process of writing code with Python to automate tasks is also known as scripting. You can use automation to scan large volumes of data to check for errors or duplicity. You can also automate the search and download of online content.
- Web development
Python is also popularly used in web development. This includes the back-end functions of web development including URL routing, data transmission between servers and overall security. Common frameworks for web development within Python include Flask and Django. Software engineers, DevOps engineers and full stack developers are some roles that routinely use Python for web development.
- Software testing
Developers can use Python for automating the testing of new software. You can check for bugs and test new features more efficiently.
Pros and Cons of Python
|Easy to use- simple syntax makes it ideal to read and understand by beginners||Not well suited for mobile computing|
|Versatile- can be used for multiple applications||Underdeveloped database access layers|
|Open source||Run-time errors due to dynamically typed code|
|Growing archive of libraries and modules||Uses large amounts of memory. Not suitable for memory optimisation|
- Difficulty Level: 2/5
- Popularity Rank: 4/5
- Front-end web development
- Back-end web development
- Game development
- Artificial Intelligence (AI) and Machine Learning
|Compatible with most other languages and can be used for multiple applications||Debugging is not as efficient as other C+ or C++ editors|

- Popularity Rank: 4/5
What is SQL?
SQL (pronounced Sequel) is a programming language that is used to communicate with relational databases. These are databases where data is stored in columns and rows that allow you to analyse data in relation to one another.
It would take very long to access large databases without SQL. SQL uses keywords known as SQL statements to easily access and edit relevant data. The main functionality of SQL is CRUD. This is an acronym for Create, Read, Update, Delete.
What is SQL used for?
- Accessing Relational Data
SQL is commonly used for back-end updates and data processing on websites. Facebook routinely uses SQL for these purposes. Given its use in communicating with relational databases, SQL is used by most companies that need to store and access relational data. This includes social networking sites like Twitter, banking apps like Revolut and more.
- SEO Analysis
SEO analysts usually work with large volumes of data to analyse web traffic. It’s more efficient to use a database instead of an Excel sheet to store this data. SQL can then facilitate accessing this data in a more time-efficient way.
- Business Analysis
Business Analysts also work with large volumes of data which they analyse and sequence to provide relevant business advice to companies. These databases require SQL for optimum accessibility.
- Software Engineering
A software engineer builds software for computers systems as well as apps. Most software engineers are versed in multiple programming languages and one of the popular ones is SQL. Given the nature of the job software engineers use SQL at some point or another to access relational databases.
Pros and Cons of SQL
|Quick access to large volumes of data||Complex interface|
|User-friendly language||Some versions are expensive|
|Standardised language provides a uniform platform for all users||Constant need to update hard drive space as data volume grows|
|Portable - can be used on laptops, PCS independent of operating systems||Doesn't grant full control over databases due to hidden business rules|

What is C++?
C++ is a general-purpose programming language. It is used to build large infrastructures that are run on limited space and energy resources. C++ can directly make changes on the machine that it is run on.
This allows developers to edit and perfect their codes to run smoothly in all environments. This is regardless of hard drive storage or the power supply to run the application. For these reasons C++ is one of the top programming languages chosen by developers.
What is C++ used for?
- Operating systems
C++ is used in all major operating systems including MacOS and mobile operating systems like iOS. Operating systems should be fast and capable of managing system resources. C++ allows developers to edit their codes to make even the minutest elements of an OS more time efficient.
C++ is used to build major databases like MySQL that are popularly used by applications like Netflix and YouTube.
- Web browsers
C++ is used to build back-end code for popular web browsers like Mozilla Firefox, Safari, and Chrome. Back-end code as we know involves getting data from remote servers and displaying the relevant content on the web pages. C++ facilitates the speedy transmission of this data.
- Google search engine
Google’s search engine uses C++ to make sure search results are displayed in minimal time. It also uses C++ to power its AI and machine learning algorithms to ensure you get the most relevant results.
Pros and Cons of C++
|Portability - can be run on different platforms||Complex to learn|
|Allows low-level manipulation of data||Doesn't support built-in code threads - can make the process slower|
|High scalability||No garbage collector to filter out unwanted data|
|Offers large community support for learning||Low flexibility - C++ is very rigid about syntax so minor fault shows multiple errors|
