What it does

Inferno is a fast, React-like JavaScript library for building modern user interfaces with a small footprint and high performance.

When to use it
  • •When you need to build a complex UI component that requires high performance and optimization
  • •When you want to leverage a React-like API without the overhead of a full React application
  • •When you're working on a project that requires a small bundle size and fast rendering
Ready-to-paste prompt
Render a to-do list app: `render(<TodoList todos={['Item 1', 'Item 2', 'Item 3']} />, root);`
Heads up: Inferno requires a compatible version of JavaScript (ES6+), and using older browsers may require additional polyfills or transpilation
