How was this Study Conducted?

This study aimed to categorize “dev jobs” based on their programming language requirements accurately. To achieve this, job titles were the primary criteria for categorization. Only jobs explicitly specifying a programming language were included. For instance, a job titled “React Developer” was categorized under JavaScript/TypeScript, while a generic title like “Backend Developer” without language specifications was excluded.

It’s important to note that one job offer could be associated with multiple languages. For example, a job titled “Full Stack Developer (Django/Angular)” contributes to both Python and JavaScript/TypeScript statistics.

In Summary

JavaScript and TypeScript are undeniably dominating the developer job market, accounting for approximately 29% of job offers that explicitly require a programming language. Python and Java follow closely behind, demonstrating robust demand. Java’s resurgence in some months suggests it’s not to be dismissed as an obsolete language.

C#, PHP, Ruby, and Go continue to exhibit consistent job demand, making them reliable choices for aspiring developers.

However, C/C++ has seen a decline in 2023 after experiencing an increase in demand in the previous year.

In this dynamic tech landscape, staying updated on the most in-demand programming languages is pivotal for career success. Tailoring your skills to align with industry demands can open doors to exciting opportunities in the world of software development.
