ES6 classes present a modern, syntactical sugar over JavaScript’s existing prototype-based inheritance. They simplify object creation and provide a clearer, more familiar structure for those from classical OOP backgrounds.
Using the `class` keyword, developers define templates for creating objects. These templates include a `constructor` method for initializing object properties and can contain other methods for shared behaviors. Here’s a simple example showcasing a `Car` class:
Example
class Car {
constructor(make, model, year) {
this.make = make;
this.model = model;
this.year = year;
}
describe() {
return `${this.year} ${this.make} ${this.model}`;
}
}
const myCar = new Car(‘Toyota’, ‘Corolla’, 2020);
console.log(myCar.describe()); // Outputs: 2020 Toyota Corolla
This example illustrates how classes streamline object creation, encapsulating properties and methods within a cohesive structure. This readability and ease of use make ES6 classes a popular choice for modern JavaScript development.
