Lets assume we got the following model

export interface UserModel {
   usename: string;
   password: string;
   email: string;
   address: string;
   phoneNumber: string
}

The address is optional and the user doesn’t add any so the value of it is null or empty string.
In cases where the value is null, empty string o even undefined for any possible reason i would like to ignore
address property from the object.

What is the best way to ignore any properties with unwanted values keeping my code strongly typed ?

PS: 1. Adding an external library to clean the unwanted values is not my goal.
2. Correlated service is a POST method and expecting a UseModel type.

the following is what i tried

function cleanUserModel(user: UserModel): UserModel {
    const cleanedUser: Partial<UserModel> = { ...user };
    
    Object.keys(cleanedUser).forEach(key => {
        const value = cleanedUser[key as keyof UserModel];
        if (value === null || value === '' || value === undefined) {
            delete cleanedUser[key as keyof UserModel];
        }
    });
    
    return cleanedUser as UserModel;
}

Works fine. BUt wondering if there is a cleaner way, with the same result!
