    Project mention: Towards a modern Web stack (by Ian Hickson, author of the HTML5 spec and current Flutter tech lead) | | 2023-02-05

    On other benchmarks I'm seeing numbers closer to 20% slower, e.g. and It's numerical code, which is the best case scenario for a native binary. It's much closer on an average web app or server workload, e.g. - you can find WASM frameworks that beat most JS frameworks on there, but that is not as impressive considering the state of the JS ecosystem. Overall, it's already under 50%, and there is still plenty of room for improvement.
