Can the Javascript Array.prototype.filter() function be applied to an array consisting of nested arrays?

When working with Javascript code, I encountered a complex array structure that is four layers deep. This array contains arrays of arrays of variables, and I need to remove specific strings of a certain value from it. I attempted to use the Array.prototype.filter() function, but it did not work as expected due to the nested nature of the arrays. Since I cannot directly target each sub-array individually for various reasons, I am seeking suggestions or alternative approaches to achieve this task.

Here is an example of the array structure in question:

[
   [
      [
         [
            1.0,
            1.0,
            1.0
         ],
         [
            0.0,
            1.0,
            1.0
         ],
         [
            1.0,
            0.0,
            0.0
         ],
         [
            1.0,
            0.0,
            0.0
         ],
         [
            1.0,
            0.0,
            1.0
         ],
         [
            t
         ]
      ],
      ...

The goal is to eliminate all instances of the "t" string within this array structure. The array's size may vary with each execution of the code. If clarification is needed or if sharing the actual code would be beneficial, feel free to request it, keeping in mind the code's length to avoid cluttering the page.

There are a total of four layers in the array structure

To access the value of the fourth nested array, you can utilize object destructuring

const result = arr.filter(([[[nestedValue]]]) => typeof nestedValue !== "string");
