Top 10 Best Programming Languages to Learn in 2025

Microsoft's typed superset of JavaScript became the most-loved language in the Stack Overflow 2025 survey for the third year running, with 78% of developers wanting to continue using it. TypeScript's adoption across Next.js, NestJS, and Deno 2.0 made it essential for full-stack web development.

Rust was voted the most admired language for the tenth year in a row by Stack Overflow respondents, and its adoption accelerated as Microsoft, Google, and the Linux kernel officially embraced memory-safe systems programming. Rust developers command salaries averaging $120K+ in the US, the highest of any language.

Google's Go language dominated cloud-native infrastructure development, powering Docker, Kubernetes, Terraform, and CockroachDB. Its fast compilation, built-in concurrency primitives, and single static binary output made it the default choice for microservices and DevOps tooling, with job postings growing 34% year-over-year.

Despite TypeScript's rise, plain JavaScript remained the most-used language globally by sheer volume of developers (67% of Stack Overflow respondents), powered by Node.js 22, Bun 1.x, and Deno 2.0 runtimes. Its ubiquity in browsers and servers makes it an unavoidable foundation for any web developer.

JetBrains's Kotlin became the dominant language for Android development after Google's full endorsement, with 95% of the top 1,000 Android apps using Kotlin. Kotlin Multiplatform Mobile (KMM) further expanded its reach to iOS, enabling shared business logic across platforms and reducing development time by up to 40%.

Apple's Swift is the mandatory language for iOS, macOS, watchOS, and visionOS development — making it essential as the Vision Pro platform matures. Swift 6 introduced complete concurrency checking and improved data-race safety, while the open-source Swift on Server ecosystem powered by Vapor continued to grow.

Often overlooked in language rankings, SQL remained one of the highest-demand skills in data engineering and analytics, with 57% of developers using it daily. Modern SQL with window functions, CTEs, and JSON support in PostgreSQL 16+ made it far more powerful than its reputation suggests for data transformation tasks.

Java remained the backbone of enterprise software, banking systems, and Android development, with an estimated 12 million active developers worldwide. Java 21's virtual threads (Project Loom) and pattern matching eliminated longtime performance and verbosity criticisms, while Spring Boot 3.x modernized the framework ecosystem significantly.

Microsoft's C# powered game development via Unity (used in 50% of mobile games worldwide), enterprise applications via .NET 9, and cloud services via Azure Functions. Its cross-platform capabilities through .NET MAUI and Blazor WebAssembly enabled full-stack development from a single language, boosting developer productivity.
