TypeScript vs competitors benchmark in 2025: who is faster?

In 2025, the programming language ecosystem has undergone significant changes. TypeScript, having strengthened its position as a standard for large web projects, is increasingly being compared not only with JavaScript but also with system languages. We analyzed the latest benchmarks to understand how well TypeScript meets performance requirements today.

Testing methodology

For the purity of the experiment, identical algorithmic tasks were used in three categories:

Computations — working with floating-point numbers (calculating Fibonacci numbers, matrix multiplication);
Data processing — parsing JSON files of 50 MB in size;
Network interaction — HTTP server with 10,000 concurrent requests.

Tests were conducted on identical hardware (Intel Core i9, 32 GB RAM, NVMe SSD). For TypeScript, the TSC 5.8 compiler was used with the --strict flag and Node.js 22 LTS.

Results: who is in the lead?

The 2025 benchmark showed unexpected results. Here are the main indicators (execution time, lower is better):

Rust — 1.2x (benchmark, fastest);
Go — 1.8x (excellent balance of speed and development);
TypeScript (Bun runtime) — 2.1x (surge thanks to JIT compilation);
Java (GraalVM) — 2.3x (stable but heavyweight);
TypeScript (Node.js) — 3.5x (expected, but with caveats);
Python 3.13 — 5.8x (slowest in pure computations).

Why is TypeScript not as bad as it seems?

Despite lagging in raw computations, TypeScript wins in I/O-bound scenarios. In the HTTP server test, Node.js showed 85,000 requests/sec versus 92,000 for Go — a difference of only 8%. And when using the Bun runtime, TypeScript almost catches up to Go (89,000 requests/sec).

The key takeaway: TypeScript in 2025 is a language for I/O-bound tasks. For CPU-bound projects (cryptography, rendering), it is better to choose Rust or Go. But for web backends, APIs, and microservices, TypeScript remains one of the fastest interpreted languages.

What has changed over the year?

Bun 1.2 — a new runtime integrating TypeScript without transpilation, giving a 40% increase in speed;
V8 12.0 — improved type optimization: function calls became 15% faster;
Ecosystem — the emergence of native Rust packages (via napi-rs) allows writing critical sections in Rust while keeping TypeScript for business logic.

Conclusions: is it worth choosing TypeScript?

If your project is a web application, API, or data processing tool, TypeScript is the optimal choice in 2025. You get development speed, type safety, and performance sufficient for 95% of tasks. For high-load systems, use a hybrid approach.
