How to utilize a single dimensional array to access a multidimensional array in JavaScript

Given the following initialized variables... (just to clarify, in the code I'm referencing, both variables are generated dynamically)

// Start of Code that CANNOT be altered.
var myPrimaryArray = [["Potato","Walrus"],42,[["Your father was a hamster", "Target"],362]];
var locationArray = [2][0][1];
// End of Code that CANNOT be altered

//What should be inserted here to retrieve "Target"?

Is there a way to ensure this will return "Target" using only the two variables provided? Without prior knowledge of how deeply nested each array is?

Answer №1

Expecting this to produce target

var myMainArray = [["Potato","Walrus"],42,[["Your father was a hamster", "Target"],362]];
var locationValue = myMainArray[2][0][1];
alert(locationValue);

result:

Target

For entertainment purposes, validate your Script:

locationValue = myMainArray [2][0][1];

Answer №2

Here's a revised version of the solution (slightly modified for stackoverflow, but should still be helpful for anyone looking for similar assistance). It may seem complex, but it should do the job.

// Start of Code that MUST remain unchanged.
var myMainArray = [["Potato","Walrus"],42,[["Your father was a hamster", "Target"],362]];
var locationArray = [2][0][1];
// End of Code that MUST remain unchanged

getArrayObjectWithLocationArray(myMainArray,locationArray)

function getArrayObjectWithLocationArray(myArray, myLocationArray){
    var myArray = stringToPositionArray(myString);
    if (myLocationArray.length > 1}{
        return getPanelWithPositionString([myArray[myLocationArray[0]], myLocationArray.splice(0,1))
    } else {
        return myArray[stringToPositionArray[0]];
    }
}
