Dependency Injection using property

 // Dependency class

class Dependency {

doAction() {

console.log("Dependency is performing an action.");

}

}

// Service class that relies on a dependency

class Service {

// Dependency is provided as a property

constructor() {

this.dependency = null;

}

setDependency(dependency) {

this.dependency = dependency;

}

doSomething() {

this.dependency.doAction();

}

}

// Creating instances and injecting dependencies

const dependency = new Dependency();

const service = new Service();

// Injecting the dependency as a property

service.setDependency(dependency);

service.doSomething();
