In my code, I am working with 3 classes ...
class1 {
constructor(a, b, c) {
this.a = a;
this.b = b;
this.c = c;
this.toClass2 = function() {
// TODO: return this as an instance of class2;
// the conversion would remove the unwanted 'b' property
}
this.toClass3 = function() {
// TODO: return this as an instance of class3;
// the conversion would remove the unwanted 'a' property
}
}
}
class2 {
constructor(a, c) {
this.a = a;
this.c = c;
}
}
class3 {
constructor(b, c) {
this.b = b;
this.c = c;
}
}
The following statements are accurate ...
- It is possible for class1 to extend class2
- It is also possible for class1 to extend class3
However, class1 cannot simultaneously extend class2 and class3 due to JavaScript's lack of support for multiple inheritance. This would result in the derived class having 4 properties instead of the desired 3.
Class2 is a subset of class1's properties
- Class3 is a subset of class1's properties
QUERY: How can I effectively implement these classes in JavaScript or TypeScript to ensure that the toClass2 and toClass3 conversion methods operate correctly? Are there any specific design patterns that could be utilized for this scenario? Thank you
