8 Programming Languages in High Demand in 2023

Which programming language will be in high demand in 2023? Should I study Python or Java in 2023? Let us investigate!

Today, the demand for software engineers is at an all-time high. For those looking to progress their technical careers, it is essential to be proficient in coding languages. According to the US Bureau of Labour Statistics, the demand for software engineers, including software developers, is projected to increase by a staggering 22% between 2022 and 2030, in comparison to a mere 4% for other occupations.

If you are looking to advance your skills as a developer and secure a successful future, it is essential that you familiarise yourself with the most popular programming languages. To gain an understanding of the various levels and types of programming languages, as well as the methods used to measure their popularity, before we explore the best programming languages to learn in 2023.

Programming language levels

In order to construct instructions for computers, each programming language has a specific purpose, syntax, and set of keywords. The primary components of programming languages typically consist of the following layers:

Languages of low level

Low-level programming languages, such as machine code, assembly-level languages, BASIC, FORTRAN, Cobol, and C, provide limited abstraction from a computer’s set of instructions. Programs written in these languages are not easily transferrable to other systems and are often difficult for humans to interpret or understand.

Advanced languages

High-level programming languages, such as Java, PHP, C#, and Swift, offer robust abstractions that significantly simplify the process of problem solving. Moreover, these languages tend to be less prone to errors and their code is not dependent on the type of machine used. Additionally, these languages are relatively easy to learn and maintain, making them ideal for a variety of applications.

Programming language types

  1. Languages for procedural programming

    In order to address a given issue, procedural programming languages are used to execute a sequence of instructions. These languages are distinct from functional programming languages in that they involve the utilisation of multiple variables, intricate loops, and components. Examples of procedural programming languages include BASIC, FORTRAN, C, and Java.
  2. Languages for functional programming

    In order to perform computations, a functional programming language focuses on the result that needs to be achieved rather than the process used to achieve it. This programming language does not make use of control structures such as loops or conditional expressions. Popular examples of functional programming languages are Python, Haskell, Clojure, Erlang, and Lisp.
  3. Languages for object-oriented programming (OOP)

    Object-oriented programming (OOP) is a programming language style that divides software into manageable code designs known as classes. Each class serves as a template for creating individual instances of objects, which can then be manipulated through the encapsulation of data and functions within the class. Popular examples of OOP languages include Java, C++, Python, and JavaScript.
  4. Programming languages for scripting

    Scripting programming languages are utilised to make use of run-time instructions, enabling them to interconnect and communicate with external programs and applications. These languages are extensively used in a variety of different contexts, such as web applications, multimedia, gaming applications, and system management. Popular examples of scripting programming languages include Python, Ruby, Node.js, Perl, and Bash.
  5. Programming logic

    Logic programming is a type of programming which is based on formal logic. By utilising facts and logical inferences, logic programming can be used to perform computations. Examples of logic programming languages include Prologue, Answer Set Programming (ASP) and Datalog, all of which are designed to express facts and rules about a particular problem area.

Top indices for tracking coding language metrics

Certain tools, such as indexes, can be beneficial when attempting to comprehend a particular topic; in this case, which programming language is the most widely used? These indexes evaluate programming languages based on criteria including, but not limited to, the language’s popularity, reliability, and ease of use.

  • Search engine and social media platform rankings
  • Job postings referencing the language
  • Language-specific open-source projects
  • Language-related videos
