Get the max depth of a multi-dimensional array
const peekdepth = require('peekdepth');
let parentArray = ["parent"];
let childArray = ["child", parentArray];
let grandchildArray = ["grandchild", childArray, parentArray]
childArray.push(grandchildArray);
parentArray.push(childArray);
console.log('grandchildArray:', grandchildArray);
console.log('depth:', peekdepth(grandchildArray));
Output:
grandchildArray: [ 'grandchild',
[ 'child', [ 'parent', [Circular] ], [Circular] ],
[ 'parent', [ 'child', [Circular], [Circular] ] ] ]
depth: 3
