Get array's depth in JavaScript

Question

In order to get the array\'s depth I thought I can use the flat() method like so:

Answer 1

Convert the array to string lets assume We are given a string having parenthesis like below “( ((X)) (((Y))) )” We need to find the maximum depth of string, like 4 in above example. Since ‘Y’ is surrounded by 4 balanced parenthesis.

Take two variables max and current_max, initialize both of them as 0. Traverse the string, do following for every character a) If current character is ‘(’, increment current_max and update max value if required. b) If character is ‘)’ means we previously had a ‘(’ character so decrement current_max without worry but dont reduce max value .

If current_max is greater than max then update max value to current_max at that instance. after traverse is completed the max is is the depth of the array.
