What is the best way to cycle through objects rather than arrays?

Is it possible to retrieve JSON data from the following URL ? Specifically, I am interested in getting information on objects such as "uf", "ivp", and so on to display them in a table or list. The challenge is that this data is not presented in an array format. How can I iterate over these objects?

{
    "version": "1.5.0",
    "autor": "mindicador.cl",
    "fecha": "2018-10-24T17:00:00.000Z",
    "uf": {
        "codigo": "uf",
        "nombre": "Unidad de fomento (UF)",
        "unidad_medida": "Pesos",
        "fecha": "2018-10-24T04:00:00.000Z",
        "valor": 27413.56
    },
    "ivp": {
        "codigo": "ivp",
        "nombre": "Indice de valor promedio (IVP)",
        "unidad_medida": "Pesos",
        "fecha": "2018-10-24T04:00:00.000Z",
        "valor": 28523.73
    }
}

I want to iterate through each object like "uf", "ivp", etc. Is there a way to achieve this even though it's not in array form?

This is the method for my service:

search(): Observable<Object> {
    const queryUrl = this.apiUrl;
    return this.http.get(queryUrl);
  }

It is important to properly handle the JSON object received from an HTTP GET request by parsing it and treating it as an object. This allows you to easily access each member of the JSON object.

this.retrieveData().subscribe(response => {
    let jsonData: any = JSON.parse(response);
    console.log(jsonData);
    // loop through jsonData members for further processing
});

Loop through the response object and extract only the values that are considered objects.

for(const property in responseObject) {
    if(typeof responseObject[property] === 'object') {
        console.log(responseObject[property]);
    }
}
