That’s strange, I thought the point of React was to make websites slow and laggy so you can save on server costs by just serving json after the initial payload.
There's nothing on the web even approaching 1990s desktop applications. Specially if you care about latency, precision, and text inputs not randomly eating what you type.
Even with the wonkiness, the web is usually worth using because of the access you get to big amounts of data and backend servers providing nice services.
