The article sets out to prove the predictability of WASM's performance, and not necessarily a performance gain wrt js.
> This confirms what we laid out at the start: WebAssembly gives you predictable performance. No matter which language we choose, the variance between browsers and languages is minimal
If you're not hyped about WASM, it's probably because your app and customer base's browser preferences are on the js engine's JIT happy-path, which could hold true for most apps. There could very easily be a js path that is significantly worse in performance on chrome, just saying, 70% market share is both a blessing and a curse.
Another major reason for WASM hype is for C#, Rust, C, C++, Go devs to reach parity with js in terms of web accessibility. Frameworks like Blazor (from MSFT) have taken all the best practices & advantages of React and made them available to C# devs.
