Today it is easy to build web apps. But it turns out that the easy way to build a web application is usually not a performant way. Developers are often under time constraints, so they don't have time to build things performantly. What if you had a framework where the easy and performant ways are one and the same? Such a framework would have to make different assumptions. But the best outcome would be if the developers could develop their code with current development style but get performant applications. This is the promises of Qwik.
