Hightlight.js supports `wasm` ([WebAssembly](https://en.wikipedia.org/wiki/WebAssembly)) as of [2022-07-13](https://highlightjs.org/#news-148) For our hosted site ([SWI-Prolog](https://swi-prolog.discourse.group/)) added both `wasm` and `webassembly` ([ref](https://swi-prolog.discourse.group/admin/site_settings/category/all_results?filter=syntax)) but the representation did not change. ([ref](https://swi-prolog.discourse.group/t/hightlight-js-wasm-test-pag/5671)) Is there anything I am missing? ---

**Follow-up** In checking to see if highlight.js **wasm** is now working on our site ([SWI-Prolog](https://swi-prolog.discourse.group/)), it appears to be working. ([ref](https://swi-prolog.discourse.group/t/hightlight-js-wasm-test-page/5671)) I could not find the change in the [code](https://github.com/discourse/discourse) on GitHub but the effect speaks for itself. Thanks. ๐Ÿ™‚ ---

Yes, last week I did upgrade Discourse to the latest version of HighlightJS, so we have all features of their current version. ---
