8 In-Demand Programming Languages to Learn in 2023

By May 19, 2022 7 min read

Which programming language is in-demand in 2023? Should I learn Java or Python in 2023? Let’s find out!

Software developers are in huge demand today. And so, developers must be proficient in coding languages to supercharge their engineering careers. According to the U.S. Bureau of Labor Statistics, the demand for software developers, including software engineers, will increase by 22 percent between 2022 and 2030 compared to four percent in other careers.

As a developer, if you are looking to enhance your skills for a promising future, then learning the most popular programming languages is very critical. Before we dive into the best programming languages to learn in 2023, here is a quick understanding of the levels and types of programming languages and the tools used to measure the popularity of the programming languages.

Levels of programming languages

Each programming language has its own purpose, syntax, and keywords to create the instructions. The main levels of programming languages are:

Low-level languages

Low-level programming languages, machine code, or assembly-level languages provide low abstraction from a computer’s set of instructions. Programs written in low-level languages are non-portable and not readable by humans. Some low-level programming languages are Assembly, BASIC, FORTRAN, Cobol, and C.

High-level languages

High-level languages have robust in-built abstractions that make problem-solving simple. These languages produce bug-free programs. High-level language codes are independent of the computer type. These languages are user-friendly. What’s more, learning and maintaining such languages are easy. Some high-level programming languages are  Java, PHP, C#, and Swift.

Types of programming languages

  1. Procedural programming languages

    Procedural programming languages involve executing a sequence of instructions to solve a problem. These programming languages use multiple variables, heavy loops, and elements that segregate procedural programming languages from functional programming languages. Some examples of procedural programming languages are  BASIC, FORTRAN, C, and Java.       

  2. Functional programming languages

    A functional programming language uses mathematical functions to perform computations. The language focuses on what to solve rather than how to solve it.  This programming language does not support controls like loop and conditional statements. Some examples of functional programming languages are Python, Haskell, Clojure, Erlang, and Lisp.

  3. Object-oriented programming languages (OOP)

    Object-oriented programming language structures the software into simple, reusable pieces of code blueprints. These code pieces are usually referred to as Classes. Classes create individual instances of objects. Object-oriented programming languages help wrap data and functions in a class. Some examples of OOP languages include  Java, C++, Python, and JavaScript.

  4. Scripting programming languages

    Scripting programming languages use instructions for a run-time environment. These programming languages integrate and communicate with other programming languages. Web applications, multimedia, gaming applications, and system administration use scripting languages. Some examples of scripting programming languages include Python, Ruby, Node.js, Perl, and Bash.

  5. Logic programming

    Logic programming is based on formal logic. In logic, with available data, the execution of programming computation happens with logical inferences. Programs represented with logic programming are sentences in a logical form expressing facts and rules of a problem domain. Examples include Prolog, Answer set program (ASP), and Datalog.

Top indices to track the metrics of coding languages

Certain tools, such as indexes, help understand: Which is the most popular programming language? These indices analyze programming languages based on:

  • Ranking in search engines and social media platforms

  • Job advertisements mentioning the language

  • Open-source projects in the given language

  • Videos on the language

  • Students enrolled to learn the language.

Indices to track the metrics:

  • PYPL Index

    In the PYPL Popularity of Programming Language index, the metrics are based on Google Trends, reflecting the developers’ search patterns for a particular programming language’s tutorials.
    The top four ranked coding languages by PYPL in 2022 are Python, Java, JavaScript, and C.

  • TIOBE Index

    TIOBE Programming Community Index ranks the top languages based on the number of searches done in popular search engines like Google, YouTube, Bing, Wikipedia, Amazon, and more.
    The top four languages with the highest ratings by TIOBE are Python, C, Java, and C++.

  • IEEE Spectrum

    IEEE generates rankings combining 11 metrics from the top eight sources like Google, GitHub, Twitter, Stackoverflow, Reddit, Hacker News, Career Builder, and IEEE Xplore Digital Library. Searches are sorted on the basis of trending, job searches, and custom ranking.
    The top four languages ranked by IEEE in 2021 are C, C++, Java, and JavaScript.

  • Stackoverflow Developer Surveys

    Stackoverflow is an in-demand Q&A website for developers. The top four languages ranked by Stackoverflow in 2021 are JavaScript, HTML/ CSS, SQL, and Python.

What are the best languages to learn?
After a basic understanding of the programming levels, types of programming languages, and indices to analyze their popularity, let’s dive into the best programming languages to learn in 2023.

  1. Python

    For years, Python has remained the most popular programming language. Python’s popularity grew when big tech companies like Netflix, Facebook, and Khan Academy started using it as their major programming language.

    Python can do several tasks, from simple scripting to advanced web applications and artificial intelligence. Google’s TensorFlow is a Python-friendly open-source machine learning platform.


    Python is the best data science tool that makes machine learning easy and effective. Python job roles have the highest number of listings. Ten thousand on Glassdoor and about 14,000 on Indeed!

  2. Java

    Java is one of the oldest and most widely used programming languages across the globe. Java is the top programming language for DevOps, virtual reality, big data, mobile chatbots, and continuous integration.

    Android accounts for 85 percent of the mobile market share, with Java as the main programming language. Top companies like Airbnb, Google, Netflix, Instagram, Uber, Amazon, and Spotify use Java in their tech stacks.

    Why Java is one of the best languages to learn for software development roles? Java is downloaded one billion times a year. It is the go-to programming language for 97 percent of enterprises, which is more than any other programming language. Java developers are in high demand, as most businesses want to build mobile applications for their products or services.

  3. JavaScript

    There are over 1.8 million websites worldwide, and more than 95 percent of these websites use JavaScript. JavaScript gave life to the browser experience by creating web pages with interactive elements. JavaScript allows users to set up dynamic and interactive content, animated graphics, and complex features on the website.

    Top web browsers like Google Chrome and Apple Safari support JavaScript.  Mobile and web apps are developed with JavaScript frameworks. Apart from apps and websites, web servers and backend infrastructure are developed with the JavaScript runtime environment, Node.js.

  4. TypeScript

    Microsoft released TypeScript in 2012 as a “typed” version of JavaScript. TypeScript is a superset of JavaScript supporting JavaScript libraries and programs. Advanced features in TypeScript like type-checks provide quick validation and ensure that the codes typed are free of errors.

    Typescript provides additional syntax to JavaScript to support better integration with an editor. According to the 2021 State of JS survey, 69 percent of survey respondents use TypeScript now compared to 21 percent six years ago.
