Only a junior developer deals in absolutes. Web workers are sometimes the answer, and if you can work within their constraints, will free up your main thread and speed up your SPA or rendering.
Web workers definitely have their place to be useful. I think we can just take it as "Web workers weren't the right solution for this".
Still an interesting read.
I would also be wary of any code I wrote after 16 years (though some I do... the very pure no dependency stuff!)
In 2 years that'll be 3x8 years and I hope to pass the audition.
