1. What is Million.js?

Million.js is a library to speed up React components. It's touted that React component performance can be improved by up to 70%[^1^].

2. How to Install Million.js

Million.js can be easily installed via npm. Just run the command below.

npm install million

3. Basic Usage of Million.js

The basic usage of Million.js is to simply wrap your React component with a function called block. Here's an example.

import { block } from "million";

function Lion() {
  return (
    <img src="https://million.dev/lion.svg" />
  );
}

const LionBlock = block(Lion);

In this way, you can speed up your React components using Million.js.

However, at this point, it cannot be used with UI component libraries, and there are some restrictions such as the spread syntax cannot be used when passing props to components[^1^].

4. Performance Improvement with Million.js

Million.js is not a substitute for React. It works with React to improve React's performance. It uses its own virtual DOM to increase rendering speed and optimize re-rendering.

Optimization of re-rendering is realized by a mechanism called block virtual DOM. This consists of 'static analysis' that parses the virtual DOM and extracts dynamic parts, and 'dirty check' where the DOM is directly updated when the state changes[^1^].

As for the specific performance improvement values, it may greatly depend on the type of application, the complexity of the React components used, and how you use Million.js. Therefore, the best way to get specific figures is to conduct benchmark tests on your own application.

5. Conclusion

Million.js is a powerful library to speed up React components. It optimizes rendering speed using its own block virtual DOM and makes re-rendering efficient. Further performance improvements and relaxation of restrictions can be expected in future updates.
