No, no the browsers deprecated it yesterday.. You are supposed to add a webasm shard, containing the operation system for the animations.

I'm not entirely sure whether you're joking

He is joking because webassembly had been deprecated today in favor of Punch cards

Sorry, but browsers (and thus webassembly) have been deprecated in favor of Bing Chat. There's a W3C draft standard being written up by Sam Altman.

Creating something like the homepage of animejs.com without an animation library today is still quite challenging.

Browsers are missing a long list of features available in modern JS animation libraries like Anime.js and especially GreenSock. For simple and short transitions/animations CSS will take you a long way though.
