Some of you might have heard about preact and may have even played around with it. Let’s dig a little deeper and explore the factors that make preact awesome. We will look at the advantages of preact over react, how easy it is to get up and running a project using preact-cli.


Preact is a 3KB alternative to React with the same API. It’s also one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation.

3) What makes preact different from react?
4) How to swap a project from react to preact
5) Using preact-compat for compatibility between preact and react
