WASM vs JS Performance

The cluster discusses the performance differences between WebAssembly (WASM) and JavaScript in browsers, including benchmarks, speedups for compute-heavy tasks, limitations with DOM manipulation, and comparisons to native code.

WASM is more efficient than JS...

With WASM it might actually run faster in the browser as well.

Are there benchmarks where the wasm engine of a browser beats the Js engine of the same browser in compute heavy code?

what if wasm become production ready... dont u think that cpu intensive will be native and difference will be somewhat closer?

metreo • Jan 6, 2021 • View on HN

wasm provides more than _just_ a speed improvement

tempaccount420 • Mar 24, 2024 • View on HN

Even WASM doesn't have native performance, so I question this claim.

Can we save more CPU time if we use wasm to replace js?

Cshelton • Mar 15, 2016 • View on HN

No, most things will still be done in javascript as the benefit of doing it in Wasm is negligible.

steventey • Aug 26, 2022 • View on HN

wow, had no idea Wasm is that much faster than JS

dboreham • Jun 24, 2021 • View on HN

Why would someone think that the purpose of WASM is to speed up JavaScript?
