In less than a decade, i'm already guessing less than 5 years, WASM will come out with a viable frontend solution that will actually be groundbreaking.
The battles between frontend philosophies in javascript will look like child's play then.
I'm not going to waste anymore time switching FE frameworks (Jquery->Angular->React), as I've found that it's been quite useless (Although I really liked Solid - shame their animation libraries suck and the overall environment isn't mature enough).
I'm happy with React.
Performance isn't an end all be all.
Svelte doesn't have a chance to match the hiring pool of React, nor will Svelte Native ever compete with React Native in maturity.
In 5-7 years, we will be talking about ending the use of Javascript on the Frontend, So i really don't care about reactivity.
The same prediction has been made for the last 25 years. Having seen the rise and fall of VBScript, Flash, Silverlight, Java applets, and countless others, I would not be so blasé as you about the imminent demise of JavaScript. There is a profoundly strong possibility that you are dead wrong.
almost with many things in software development to be honest.
