Top 8 Most Demanded Programming Languages in 2023 (Based on DevJobsScanner Data)

In the past 17 months (January 2022 to May 2023), DevJobsScanner analyzed more than 14 million developer job postings, filtered those with explicit programming language requirements, and determined the eight languages with the greatest demand in 2023.

1. JavaScript / TypeScript

JavaScript remains the most popular language, while the rise of TypeScript has further boosted its dominance. TypeScript’s popularity has increased in recent years, especially in modern frameworks such as Angular and NestJS. DevJobsScanner found 915 000 job listings requiring JavaScript or TypeScript, representing about 29% of all language‑specific positions.

2. Python

Python ranks as the second‑most demanded language in 2023. Its versatility—from scripting and server‑side development to data analysis—has driven its strong demand, with 603 000 job postings (about 20% of language‑specific jobs). Python also benefits from one of the largest developer communities.

3. Java

Java holds the third spot, with 546 000 job opportunities (approximately 17% share). Since its creation in 1995, Java has remained popular; although newer languages like Kotlin have emerged, Java’s extensive ecosystem—especially frameworks such as Spring—keeps it firmly in the top three.

4. C#

C# ranks fourth, with 375 000 postings (about 12%). It is a general‑purpose, multi‑paradigm, object‑oriented language created to address shortcomings of C++. Its most common use is with the .NET framework, and it is also heavily used in Unity for game development.

5. PHP

PHP, created 27 years ago, remains the fifth‑most demanded language, accounting for roughly 10% of all developer positions. It is primarily used for web development with frameworks such as Laravel and content‑management systems like WordPress.

6. C/C++

C and C++ together form the sixth‑most demanded group. After decades of evolution, they remain widely used in games, servers, databases, and even space probes. However, demand slowed in 2023, dropping from nearly 13% in February to about 7% in May.

7. Ruby

Ruby ranks seventh with 134 000 job listings (approximately 4%). Its most common use is with the Ruby on Rails web framework, and it is employed by large tech companies such as Twitter, Crunchbase, and GitHub.

8. Go

Go, created by Google 12 years ago, is a younger language designed for multi‑core, networked machines and large codebases. Its popularity is slowly rising, and DevJobsScanner predicts it could break into the top five by the end of 2023. Companies such as Uber and Twitch already use Go.

Summary

JavaScript and TypeScript together account for 29% of all language‑specific job opportunities, meaning roughly one in three developer positions requires one of these languages. Python and Java remain the second and third most demanded languages, with Java narrowing the gap to Python. C#, PHP, Ruby, and Go show stable demand, while C/C++ appears to be on a declining trend in 2023.
