Answer 1

          for(i in 0 until response.length()) {
                val item = response.getJSONObject(i)
                if (item["type"] != "como") {
                    Log.d("JSON_SUCCESS", item["type"].toString())
                }
            }

Answer 2

for(i in 0 until response.length()) {

    val item = response.getJSONObject(i)

    if (item["type"] != "como") {

        Log.d("JSON_SUCCESS", item["type"].toString())
    }

}
