I find this idea interesting ‘These are possible in JavaScript in browsers, but implementation quality varies a lot and many web devs just never bother.’

Do you have any examples that you consider good implementations? I ask because tables seem to be the biggest offenders of slow components in say Angular / PrimeNG. I am going to a legacy app soon that is being updated (Angular but not PrimeNG). Would like to see if we can build a feature rich table that is more performant than the PrimeNG one that I know looks amazing but is the cause of many headaches.

NOTE: its not Angular or PrimeNG specifically that make the tables slow/hogs, but the amount of DOM elements inside and some of the implementation details that I disagree with (functions that are called withing the HTML being evaluated every tick). Would be great to see if this idea of a ‘recycler widget’ can help us. Cheers.
