What is inferno?
Inferno is a fast, lightweight, and highly performant JavaScript library for building modern user interfaces. It is similar to React in terms of API and functionality but is optimized for speed and performance.
What are inferno's main functionalities?
Component Creation
Inferno allows you to create components using a class-based approach similar to React. This example demonstrates how to create a simple component that renders a 'Hello, Inferno!' message.
const { Component } = require('inferno');
class MyComponent extends Component {
render() {
return <div>Hello, Inferno!</div>;
}
}
module.exports = MyComponent;
JSX Support
Inferno supports JSX syntax, which allows you to write HTML-like code within your JavaScript. This example shows how to use JSX to create a simple component.
const Inferno = require('inferno');
const MyComponent = () => (
<div>
<h1>Welcome to Inferno</h1>
<p>This is a JSX example.</p>
</div>
);
module.exports = MyComponent;
State Management
Inferno provides state management capabilities similar to React. This example demonstrates a simple counter component that increments the count when a button is clicked.
const { Component } = require('inferno');
class Counter extends Component {
constructor(props) {
super(props);
this.state = { count: 0 };
}
increment = () => {
this.setState({ count: this.state.count + 1 });
};
render() {
return (
<div>
<p>Count: {this.state.count}</p>
<button onClick={this.increment}>Increment</button>
</div>
);
}
}
module.exports = Counter;
Lifecycle Methods
Inferno supports lifecycle methods that allow you to hook into different stages of a component's lifecycle. This example demonstrates the use of `componentDidMount` and `componentWillUnmount` lifecycle methods.
const { Component } = require('inferno');
class LifecycleDemo extends Component {
componentDidMount() {
console.log('Component mounted');
}
componentWillUnmount() {
console.log('Component will unmount');
}
render() {
return <div>Check the console for lifecycle logs.</div>;
}
}
module.exports = LifecycleDemo;
Other packages similar to inferno
react
React is a popular JavaScript library for building user interfaces, developed by Facebook. It offers a similar component-based architecture and lifecycle methods as Inferno but is more widely adopted and has a larger ecosystem.
preact
Preact is a fast 3kB alternative to React with the same modern API. It is similar to Inferno in terms of performance and size but has a slightly different approach to handling components and state.
vue
Vue.js is a progressive JavaScript framework for building user interfaces. It offers a more opinionated approach compared to Inferno and includes features like directives and a built-in state management system.
