Top 6 Programming Languages Used In Data Science

There are several ways that programming is used in data science, ranging from automating data clean-up and data set organization to creating databases and fine-tuning machine learning algorithms. Across job functions, data science relies on programming.


This article will explain to you the top 6 programming languages essential in data science.

  • Python


Python is a popular, general-purpose programming language. It is open source and object-oriented, grouping data and functionality together to create flexibility and composability. It is commonly used in data science for data processing, applying data analytics algorithms, and educating machine learning and deep learning algorithms. It is a great option for beginners due to its simple English syntax and multiple data structure support.


Python is a good choice if you want to keep your career in data science and AI which can be mastered through the best data science certification course in Delhi. 

  • SQL

Structured data can be manipulated using SQL or structured query language. You may have trouble finding the data you need in a large dataset that contains millions of rows. SQL is a querying language that allows you to query, locate, and verify large data sets. Because of their domain-specific nature, relational databases are simple to handle. Data professionals must learn scripting with Python, fundamental statistics, and SQL, regardless of which route they take, said Gwen Britton, Associate Vice President of Southern New Hampshire University Global Campus STEM & Business Programs and instructor for edX MicroBachelors in data management and business analytics programs. SQL must be learned if you are using relational databases in data science.

  • Scala

Scala, an extension of Java, is an advanced data science language that runs on the Java Virtual Machine and compiles Java bytecodes. Scala was created to address Java’s shortcomings and is a more sophisticated, elegant language. Because of its interoperability, Java virtual machines are able to handle siloed data. Scala is an open-source, high-performance framework that delivers enterprise-level data science. Its library and support libraries are extensive and available in used Integrated Development Environments (IDEs). Concurrent and synchronized processing is also available.

Data scientists can use Scala to analyze large datasets without bogging down the system because systems developers frequently use Scala to analyze data.

  • R

R is built to manage big data sets and intense computation through RStudio. R’s statistics-focused syntax is friendly to researchers with a statistical background, and its visualizations are capable of visually communicating results. 

If you are a data scientist with some programming experience or a novice data scientist seeking to make a name for yourself in the research field, learn R. You’ll also recognize R’s structure if you are a statistician. 

  • C/C++

C/C++ provides excellent capabilities for building statistical and data tools. This knowledge will also apply to Python and be scalable for performance-based applications. C/C++ is also surprisingly helpful because it compiles information quickly. It creates really useful tools and enables meticulous adjustment. If you haven’t previously studied programming languages, it may be difficult to learn them.


C++ provides an excellent capability for building statistical and data tools. These abilities will translate well to Python and can easily handle performance-based demands.

  • JavaScript

As a web development language and an application, JavaScript is a big part of the business world. With a good variety of packages and superb web integration, it’s a great data scientist choice. Data scientists can utilize the tremendous range of libraries to build interactive dashboards, visualizations, and just about anything else. It functions well as a secondary data science language but is scalable. 


If you’re a budding Data scientist who wants to learn JavaScript to better work with data, this is a good time to do so. Learn these languages with the best Data science course in Delhi and become a pro at the coding required for data science.
