Has anybody used the Houdini and the Worklet API? It looks like a cross between Service Workers and WAAPI… Is there any indication that these might be modified or deprecated now that they have browser support? (like WC v0) ---

TBH I don’t know why Worklets are not big… To be able to run browser animations, on the GPU, with access to the DOM in another thread while your main thread handles everything else seems like a huge performance boost. For example something like @kirupa 's snowflake animation or even a particle animation that doesn’t block the main thread… Am I missing something… Mozilla says it has browser support but they don’t even have examples for animation or layout Worklets…
