JavaScript (Node.js) Back on Top: What Developers Are Saying in 2025

JavaScript (Node.js) topped the StackOverflow ranking of favorite languages: what is behind the success?

The annual StackOverflow developer survey is one of the most authoritative snapshots of the IT industry. In 2025, the results once again confirmed the global dominance of JavaScript, and its server-side environment Node.js took leading positions in the "most loved technologies" category. Let's figure out why developers around the world are putting Node.js on a pedestal.

Why is Node.js more than just JavaScript?

Node.js allows you to run JavaScript on the server, turning it from a client-side language into a full-fledged platform for backend development. According to the StackOverflow survey, over 65% of professional developers use JavaScript in their daily work, and Node.js is among the top three most in-demand frameworks and runtime environments.

• Versatility: One language for frontend and backend lowers the entry barrier and simplifies project maintenance.
• Asynchronicity and speed: The event-driven model of Node.js is ideal for high-load applications and real-time services (chat bots, streaming, APIs).
• Huge community: npm is the largest package manager, with over 2 million libraries available. A solution to any problem already exists.

What do the survey data say?

In 2025, the question "Which language do you love the most?" brought Node.js (JavaScript) first place with a result of over 72% positive responses among those who had worked with it. For comparison, Python, Rust, and TypeScript take second to fourth places, but it is the JavaScript ecosystem that received the largest increase in the "would like to use again" category.

• The average salary of a Node.js developer increased by 12% compared to last year.
• One in five respondents indicated that they started their career by learning JavaScript and Node.js.
• Node.js leads in the categories of microservice architecture and serverless development.

Who is Node.js suitable for?

Node.js is an excellent choice for startups and large corporations: it is used by Netflix, LinkedIn, Uber, and NASA. If you are a web developer and want to expand your stack, Node.js is a logical step. It is also popular among Python developers who value it for its execution speed and ease of integration with databases.
