Miško Hevery describes the very fast Qwik JS

Miško Hevery is the CTO of builder, Online visual site designer.He is also the creator Qwik, Next-generation JavaScript framework. Before the days of Builders and Qwik, Hevery created Angular, one of the flagship JavaScript frameworks. Karma, A popular JavaScript test runner.

Obviously, Hevery has been involved in the JavaScript world for a long time. I had the opportunity to talk to him about Qwik, Builder, responsiveness challenges, speeding up web apps, helping content creators and engineers coexist.

Matthew Tyson: I’m excited to talk to you. I discovered Qwik, which led to Builder and your biography. It has a very interesting history, including the creation of both Karma and Angular. So I’d like to ask you what you think about some of the latest JavaScript trends.

Let’s start with reactivity. Reactivity is one of the most important developments of front-end code, but it’s not a perfect world.

Miško Hevery: it’s complicated. Reactivity has many excellent properties, but it also has many problems. The basic problem with responsiveness is that it requires a lot of computing resources to set up and then discard. This has a negative impact on performance and memory usage. All of this means that the framework needs to download all applications before responsiveness works.

Qwik needs to be responsive because it wants to be lazy, but at the same time it needs an approach to responsiveness that allows the framework to infer without loading the application. Qwik does this by storing the reactive subscription information in the DOM.
