Defining a TypeScript Interface for Nested Boolean Properties

Using typescript how can I define an interface to this object { "POS": { "LEGAL_PERSON": false, "PHYSICAL_PERSON": false }, "FFF": { "LEGAL_PERSON": false, "PHYSICAL_PERSON": false } }

To define a TypeScript interface for the given object, you need to create an interface that describes the structure of the object. The object has two main properties, POS and FFF, each of which is an object with two boolean properties: LEGAL_PERSON and PHYSICAL_PERSON.

Here's how you can define the interface:

interface PersonType {
    LEGAL_PERSON: boolean;
    PHYSICAL_PERSON: boolean;
}

interface MainObject {
    POS: PersonType;
    FFF: PersonType;
}

// Example usage:
const exampleObject: MainObject = {
    POS: {
        LEGAL_PERSON: false,
        PHYSICAL_PERSON: false
    },
    FFF: {
        LEGAL_PERSON: false,
        PHYSICAL_PERSON: false
    }
};

In this code:

1. PersonType is an interface that describes the structure of the nested objects (POS and FFF), which have two boolean properties: LEGAL_PERSON and PHYSICAL_PERSON.
2. MainObject is an interface that describes the structure of the main object, which has two properties: POS and FFF, both of which are of type PersonType.

This way, you can ensure that any object adhering to the MainObject interface will have the correct structure.
