How does esprima.ClassDeclaration work?

esprima.ClassDeclaration is a method provided by the esprima library that parses a string of JavaScript code and returns an abstract syntax tree (AST) representing a class declaration. The AST can then be used for further analysis or manipulation of the class structure.

class Animal {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }

  speak() {
    console.log(`${this.name} makes a noise.`);
  }
}

const dog = new Animal("Max", 3);
console.log(dog.name); // Output: Max
dog.speak(); // Output: Max makes a noise.

In this example, Animal is a ClassDeclaration that defines a blueprint for creating Animal objects with a constructor function that initializes the name and age properties, and a speak method. An instance of the Animal class named dog is then created using the new keyword, and its name property is accessed and the speak method is called.
