If your object could contain any key value pairs  you could declare an interface called keyable like   interface keyable        key  string   any      then use it as follows   let countryProviders  keyable     or let countryProviders  Array lt keyable gt

You probably have allProviders typed as object   as well  And property country does not exist on object  If you don t care about typing  you can declare both allProviders and countryProviders as Array lt any gt    let countryProviders  Array lt any gt   let allProviders  Array lt any gt     If you do want static type checking  You can create an interface for the structure and use it   interface Provider       region  string      country  string      locale  string      company  string    let countryProviders  Array lt Provider gt   let allProviders  Array lt Provider gt
