Is there a way to assign types to objects with different keys and values, but where "other" remains constant across all of them? How can this be achieved using TypeScript?
{
color: "red",
size: "small",
other: {
price: 345
discount: 10
}
}
{
ram: "4 GB",
brand: "Samsung",
other: {
price: 755
discount: 30
}
}
That scenario is typically more broad and general.
class Product {
details: {
price: number;
discount: number;
};
[key: string]: any;
}
However, if you are able to establish some boundaries and pinpoint specific instances, it would be much more effective to create a parent class with shared properties like details, and then define child classes for the specialized (yet constrained) fields, such as:
class Product {
details: {
price: number;
discount: number;
};
}
class Clothing extends Product {
size: string;
color: string;
}
class Electronics extends Product {
capacity: string;
brand: string;
}
