Nexting Class Within Class in javascript

 In Javascript we can'not directly next class within class but way to do it is as follows

Using static keyword

class OuterClass {

constructor() {

this.outerProperty = 'Hello from outer class';

this.innerClass = new OuterClass.InnerClass();

}

outerMethod() {

console.log(this.outerProperty);

this.innerClass.innerMethod();

}

static InnerClass = class {

constructor() {

this.innerProperty = 'Hello from inner class';

}

innerMethod() {

console.log(this.innerProperty);

}

}

}

const outerObj = new OuterClass();

outerObj.outerMethod(); // Output: "Hello from outer class" and "Hello from inner class"

Output:

Hello from outer class

Hello from inner class

Without static keyword

class OuterClass {

constructor() {

this.outerProperty = 'Hello from outer class';

this.innerClass = new this.InnerClass()

}

outerMethod() {

console.log(this.outerProperty);

this.innerClass.innerMethod();

}

InnerClass = class {

constructor() {

this.innerProperty = 'Hello from inner class';

}

innerMethod() {

console.log(this.innerProperty);

}

}

}

const outerObj = new OuterClass();

outerObj.outerMethod(); // Output: "Hello from outer class" and "Hello from inner class"

Output:

Hello from outer class

Hello from inner class
