Top 10 Programming Languages for Data Science

You must learn many programming languages if you are interested in joining the field of data science since one language can not solve problems in all fields. Your abilities would be incomplete without understanding the fields widely used in data science.

Demand for these languages, including Python, began to rise in the 2010s and data science growth. In reality, data science and Python skills were the necessary ingredients from 2014 to 2019, according to an Indeed report, to ensure a solid foundation in an IT career by 2020.

Several of these specifications are directly linked to a growing variety of innovations now widely embraced. Cloud amplification, augmented reality (AR), virtual reality (VR), artificial intelligence (AI), machine learning (ML), and deep learning contribute to some language requirements. In addition, different languages refer to various data science functions, such as market analyst, computer engineer, system architect, or engineering machine learning (ML).

Finally, you should be able to specialize in a certain programming language in your data science background, application system, preferences and your career path. I prefer to do data science online course to cover all the programming technologies in one shot.

Here I listed the top 10 programming languages that are used for data science all over the world.


Eighty-three percent of 24,000 data professionals found used Python in a new global survey. Python is loved by programmers and data scientist because it is a flexible and vibrant programming language. Python appears to be favoured to use iterations below 1000 for data science over R, as it ends up being quicker than R.

This is also thought to be superior to R for manipulation of the data. This language also provides excellent packages for processing natural language and learning knowledge and is inherently object-oriented.


R is a unique language and has very fascinating features that are not present in different languages. For data science applications these features are extremely significant. As a vector language, R can do many things at the same time, and functions can be added without looping to a single vector. This is used in a number of areas, from financial science to genetics, biology, and medicine, as the strength of R is harnessed.


Java has remained a favourite among desktop, cloud, and mobile developers for the past several decades. It runs on the back of an extremely sophisticated JVM (Java Virtual Machine) environment.

Java is commonly used by businesses in place of other contemporary languages, largely because of the scalability it provides. Once a Java job is found, it can develop without affecting performance. Hence, developing large-scale machine learning systems is seen as a common decision.


SQL (Structured Query Language) is a common domain language used by a relational database management system to handle the data. SQL is like Hadoop that it manages information, but the handling of information is very different. SQL tables and SQL queries are key to understanding and feeling relaxed for any data scientist. While SQL can not be used exclusively for data science, learning how to use information in database administration systems is very necessary for a data scientist.

C (C++)

C++ finds an irreplaceable location in every computer scientist’s toolbox. In addition to all existing data science applications, there is a low-level programming language overlay called C++, since it is responsible for executing the high-level code implemented in the framework. This language is clear and highly successful and is one of the quickest on the market. Being a language of low level, C++ allows data scientists to have a much broader application order.


JavaScript is an object-oriented language that was mainly used to build interactive web pages in front-end development during the 2000s. But it changed greatly during the 2010s, with the introduction of ReactJS, Angular JS, VueJS, NodeJS, and several other frameworks.

JavaScript is easy to use as there are algorithms and trends in the web browser that potential data scientists will use. This also helps users to construct interactive visualizations of data from data sets in an Internet dashboard.


Julia is yet another high-level programming language, designed for high-performance data analytics and computing. It has a large variety of applications for front and backend such as Internet programming. Julia is able to use API to integrate into services, promoting metaprogramming.

For Python, this language is claimed to be the quickest since it was designed to apply mathematical concepts such as linear algebra easily and is best done with matrices. Julia offers quick production of Python or R as she creates programs running as quickly as C or Fortran programmes.


MATLAB has a native detector, image, video, telemetry, binary and other real format support. It provides a full range of output in data and machine learning, as well as advanced methods such as nonlinear optimization, device recognition and thousands of predefined algorithms for image and video processing, financial modelling, control system design. Our physical activities in clusters and clouds adapt directly to parallel processing.
