I made a pretty cute way to traverse JSON with known structure without mapping to an object

private tailrec fun <T> traverse(map: Map<*, T?>,  i: Int, vararg keys: String): T? {
    var _i = i
    val value = map[keys[_i]] ?: return null
    if (i == keys.size - 1) return value
    return traverse(value as Map<*, T?>, ++_i, *keys)
}

traverse<String>(map, 0, "key1", "key2", "key3")
