Keeping this in view, what is Preact?

Preact is a JavaScript library that describes itself as a fast 3kB alternative to React with the same ES6 API. I'll also demonstrate how Preact works with external APIs by building a Preact app that shows the most recent debut shots from Dribbble.

Also Know, how do you use a Preactive compat? There are two different approaches to switch from React to Preact: Install the preact-compat alias. Switch your imports to preact and remove incompatible code.

Generally, the process of switching to Preact involves a few steps:

  1. Install Preact.
  2. JSX Pragma: transpile to h()
  3. Update any Legacy Code.
  4. Simplify Root Render.

Also question is, how is Preact so small?

The answer is simple—the main reason for its smaller size is that Preact is only intended to work in a browser with DOM. It has different renderer syntax from React (such as react-dom or react-native), but it's not a drawback because it is compatible with React way too.

How big is react?

React is about 100 KB and Vue is of 80 KB in size. The size of frameworks/ libraries can have a significant impact on software development projects. React needs support for certain tasks from other libraries.
