If performance, speed, and size of the application are important factors to you, Preact is the ideal option. It is mainly utilized to create advanced web apps. For instance, Uber moved to Preact in production to make its PWA lightweight and powerful.The primary difference between React and Preact is that React uses synthetic events, which are wrapped around the actual events that React has added to make all the events work seamlessly across all browsers.
Preact has discarded these for their performance and code-size issues.
It registers event handlers using the browser’s standard addEventListener. Event nomenclature and behavior are identical to those of simple JavaScript/DOM.
