Competition from faster emerging languages (Mojo, Julia, Zig, Rust)

Mojo offers Python interoperability with C-level speed; Julia dominates scientific computing; Rust leads systems programming; Zig and WebAssembly-centric languages dominate edge/IoT. Python loses use-case ownership across domains.

Single-Threaded Nature and Performance Limitations

JavaScript's interpreted, single-threaded nature imposes performance limits. While improvements via V8, Deno, and WebAssembly have helped, JavaScript is still not suitable for high-performance, multithreaded workloads like 3D simulations or large-scale numerical computing.

WebAssembly debugging difficulty and learning curve

Debugging WebAssembly code is challenging due to its low-level nature. Additionally, WebAssembly modules can be larger than JavaScript files, increasing initial load times, and developers must learn new languages like Rust or refactor existing codebases.

WebAssembly support is incomplete

Go's WebAssembly (WASM) support remains half-baked compared to Rust and TypeScript, which dominate in the WASM development arena.
