Benchmark 2025: TypeScript vs Main Competitors

The world of programming languages in 2025 has become even more competitive. TypeScript, having strengthened its position as the "web development standard," is increasingly compared not only with Python or Java but also with system languages like Rust and Go. We conducted our own analysis, based on the latest benchmarks and real projects, to understand where TypeScript wins and where it still falls short.

Key Benchmark Metrics

For the purity of the experiment, we took three typical tasks from modern development: parsing JSON (10 MB), performing 100,000 mathematical calculations, and rendering an HTML template. The following participated in the test:

TypeScript 5.7 (via Bun 1.2)
Rust 1.82 (compilation with release flag)
Go 1.23 (native build)
Python 3.13 (with JIT compilation)
Java 22 (GraalVM native-image)

Results: Execution Speed

In 2025, the gap between "fast" and "slow" languages has narrowed, but not disappeared:

Rust — absolute leader. Average task execution time is 35% faster than TypeScript on Bun.
Go — lags behind Rust by only 10–15%, but significantly wins in code simplicity.
TypeScript (Bun) — reduced the gap to Go to 20% due to JIT compiler optimization.
Java (GraalVM) — shows stable results, but falls behind TypeScript in I/O-related tasks.
Python — despite JIT, remains the slowest in this list (3–4 times slower than TypeScript).

Safety and Development Convenience

Here, TypeScript 2025 demonstrates an unexpected advantage. Thanks to new typing capabilities (like const-type parameters and improved union-type inference), the number of runtime errors has decreased by 40% compared to 2023. Rust remains the benchmark for memory safety, but the price is development time. Go and Java are in the middle, while Python still requires thorough testing.

Ecosystem and Tooling

In 2025, the TypeScript ecosystem has become even more powerful:

The package manager pnpm with workspace mode is almost on par with Rust's Cargo.
Frameworks (Next.js, Nuxt, SolidStart) automatically generate types for APIs.
Tools like Biome and oxc (Rust-based linter) reduced build time by 10 times.

For comparison: Go has an excellent standard library, but the selection of third-party packages is limited. Rust offers the best dependency management but requires more setup time. Python wins in the number of libraries for ML but loses in typing.

Verdict: What to Choose in 2025?

TypeScript is the best choice for web applications, APIs, and full-stack development, where product creation speed and type safety are important. Rust and Go remain leaders for system programming.
