since almost everybody I encounter here agrees that Javascript sucks, What should I learn to make good "web apps" with good performance ?

Here sucks is in the sense of suckless philosophy, I don't think everybody likes the suckless movement but I've seen that many people, me included, don't like how modern web apps look like (messenger and tiktok are like the worst). So if I want to make interactive web apps, what are the better technologies to not make the web shittier ?
