ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
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.
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;
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 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.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.
Inferno is a framework for building user-interface components (specifically for the browser's DOM). Inferno achieves great performance for demanding applications by using virtual DOM as a lightweight representation of the actual DOM to construct interfaces in a simple manner. However, unlike other frameworks that use virtual DOMs, Inferno does not diff the virtual DOM on each update, but rather it knows what parts of interface are static and only diffs parts that have changed. This technique allows Inferno to achieve blazingly fast DOM operations with very little overhead.
Let's start with some code. As you can see, Inferno intentionally keeps the same good (in our opinion) design ideas regarding components, one-way data passing and separation of concerns.
var message = "Hello world";
Inferno.render(
t7`<MyComponent message=${ message } />`,
document.getElementById("app")
)
Furthermore, Inferno also uses ES6 components like React:
t7.module(funciton(t7) {
class Component implements Inferno.Component {
constructor(props) {
super(props);
this.state.counter = 0;
}
render() {
return t7`
<div>
<h1>Header!</h1>
<span>Counter is at: ${ this.state.counter }</span>
</div>
`;
}
}
t7.assign("Component", Component);
Inferno.render(`<Component />`, document.body);
});
The real difference between React and Inferno is the performance offered at run-time. Inferno can handle large, complex DOM models without breaking a sweat. This is essential for low-power devices such as tablets and phones, where users of those devices are quickly demanding desktop like performance on their slower hardware.

Writing code should be fun. Browsers are getting more advanced and the technologies being supported are growing by the week. It's about time a framework offered more fun without compromising performance.
Inferno is still in early development and there are still many missing features and optimisations to be had. Do not use this framework in production environments until a stable release has been stated. Features that still need to be completed:
