Take a look at this array and its corresponding expected output:
In Javascript, is it possible to dynamically determine how many levels there are in the array ary?
var ary = ["a","b",["c","d"],"e",["f","g",["h","i"],"j"]];
Output: 3
var ary = ["a","b",["c","d"],"e",["f","g","i"]];
Output: 2
var ary = ["a","b",["c",["d"]],"e",[["f","g",["i","j"]],"k"]];
Output: 4
Below is a recursive function designed to navigate through the layers of an array while keeping track of its maximum depth. It's worth noting that this function utilizes properties attached to itself for tracking purposes.
var arr = ["a","b",["c",["d"]],"e",[["f","g",["i","j"]],"k"]];
function calculateMaxDepth(arr, start) {
//Attach depth-related properties to the function
if (start){
calculateMaxDepth.depth = 0;
calculateMaxDepth.maxDepth = 0;
}
//Determine and keep track of max depth
calculateMaxDepth.depth++
if (calculateMaxDepth.depth > calculateMaxDepth.maxDepth)
calculateMaxDepth.maxDepth++;
//Recursively handle each element in the array
for (let element of arr)
if (element instanceof Array)
calculateMaxDepth(element);
calculateMaxDepth.depth--;
//Return max depth upon reaching initial level again
if (calculateMaxDepth.depth === 0)
return calculateMaxDepth.maxDepth;
}
let result = calculateMaxDepth(arr, true);
