Recursive multidimensional array to the most subset of the method, convenient operation to take the value.

JSON is a two-dimensional array. We'll find a way to pass it to the innermost array (that is, recursion to the case of not an array, to make it easier to manipulate the value).

The instanceof array method is to determine whether an array is the case when recursive data is not an array, that is, else. The console output results are as follows:

The resulting object, not an array.

In this way, we use the data very convenient, so the key value pair should be very easy to operate.

Note: When we use recursion, we must pay attention to join the conditional judgment, otherwise it is easy to turn into a dead loop, which will make the program into the card-dead state.
