The Differences Between Solid and React

React does something different. It has a virtual DOM, and it's like the UIs, a function of state. And anytime there's any kind of change in your application in your system, it retriggers all the render functions across your whole app to figure out what the UI should look like. So that was a big innovation and it made a lot of sense. But as React changed over time, we're doing a lot more complex, crazy stuff on the web now, there's been some challenges with this model.
