Introduction

The world of programming languages is constantly evolving. Every year, new surveys and indexes reveal which languages developers are actively using, which are declining, and which are emerging as industry favorites. In 2025, Python and JavaScript remain at the top, but other languages like TypeScript, Go, and Rust are gaining significant traction.

This article explores the latest statistics on programming language usage in 2025, analyzes their adoption trends, and discusses what this means for developers, businesses, and the broader tech ecosystem.

The Data Sources

To provide a reliable overview, we combine insights from major sources:

• Stack Overflow Developer Survey 2025 — covering 85,000+ developers worldwide.

• TIOBE Index 2025 — ranking languages by search engine queries and popularity metrics.

• GitHub Octoverse (2024/2025 edition) — tracking open-source repositories and contributions.

The Most Used Programming Languages in 2025

According to the latest Stack Overflow Developer Survey (2025):

• JavaScript → used by ~66% of developers.

• HTML/CSS → ~61.9%.

• Python → ~57.9%.

• SQL → ~58.6%.

• TypeScript → ~43.6%.

• Java → ~29%.

• C# → ~28%.

Grouping the Languages

1. Web Development

• JavaScript & TypeScript dominate the frontend.

• TypeScript adoption is increasing rapidly due to its type safety and the need for large-scale projects.

• Backend frameworks using JavaScript (Node.js, Deno) keep JS relevant beyond the browser.

2. Enterprise & Backend

• Java and C# remain strong in enterprise systems, banking, and ERP solutions.

• Go is becoming a favorite for microservices and cloud-native development due to speed and simplicity.

3. Data Science & AI

• Python rules the AI/ML ecosystem, with libraries like TensorFlow, PyTorch, and Pandas.

• R remains popular in academia and statistics.

• Julia is slowly gaining adoption in scientific computing.

4. Systems & High-Performance Computing

• C and C++ are still essential for OS, compilers, and performance-critical apps.

• Rust is gaining traction as a safer alternative to C/C++, particularly in embedded systems and security-sensitive projects.

5. Mobile Development

• Kotlin is the default for Android.

• Swift is the standard for iOS.

• Cross-platform frameworks (Flutter with Dart, React Native with JS) are reducing barriers.

Why Python Continues to Lead

Python’s versatility explains its ongoing dominance:

• Easy learning curve for beginners.

• Wide adoption in AI, ML, and Data Science.

• Rich ecosystem of frameworks: Django (web), FastAPI (APIs), and countless scientific libraries.

Its 25%+ share in TIOBE and ~58% developer adoption in Stack Overflow make it the most future-proof language in 2025.

JavaScript and TypeScript: The Web’s Backbone

JavaScript remains the most widely used language. But the real story is TypeScript, which has grown to nearly half of JS adoption levels.

• TS is now essential for scalable frontend projects.

• Frameworks such as Angular, Next.js, and Nest.js are driving TypeScript usage.

• Many companies adopt TypeScript-first policies for new projects.

Emerging Stars: Go and Rust

• Go is praised for its concurrency model and simplicity, making it ideal for microservices, DevOps tooling, and cloud infrastructure.

• Rust is the fastest-growing language by adoption percentage. Its memory safety and performance are pushing companies like Mozilla, Microsoft, and Cloudflare to adopt it in production.

The Decline of Older Languages

While still in use, some languages show a gradual decline:

• PHP is less dominant, though still relevant in legacy web systems (WordPress, Drupal).

• Swift has nearly replaced Objective-C.

• Perl and COBOL survive mostly in niche or legacy contexts.

What These Trends Mean for Developers

• Beginner-friendly path: Start with Python or JavaScript.

• Backend engineers: Learn Java, Go, or Node.js.

• AI/ML enthusiasts: Python is mandatory, with optional R or Julia.

• System-level engineers: Rust is a strong choice for future-proof skills.

• Mobile devs: Kotlin and Swift remain must-haves.

Should You Still Learn PHP in 2025?

Despite the decline in popularity, PHP is far from dead. According to multiple surveys, PHP still powers a massive portion of the web — especially through WordPress, Drupal, and Joomla, which together account for over 30% of websites online.

Interestingly, some universities and colleges still choose PHP as the first programming language to teach. The reasons include:

• Simple syntax compared to languages like Java or C++.

• Immediate results when building dynamic websites.

• Huge ecosystem of tutorials, frameworks (Laravel, Symfony), and hosting support.

Pros of Learning PHP

• Quick entry into web development.

• Abundant legacy codebases and jobs maintaining them.

• Strong demand in CMS (WordPress) customization.

Cons of Learning PHP

• Less modern compared to JavaScript frameworks (React, Next.js) or Python frameworks (Django, FastAPI).

• Fewer opportunities in cutting-edge areas like AI, mobile, or cloud-native development.

👉 Verdict: PHP can still be valuable, primarily if you aim to work in web maintenance, CMS development, or freelancing. However, if your career goals involve modern web apps, mobile, or AI, it’s better to prioritize languages like JavaScript, Python, or Go.
