Using .includes to find sub-array [duplicate]

Question

I have an element i want to search for in the format of [numOne, numTwo]. i want to be able to search through an array called movesTaken two find this element.

lets assume this:

let numOne = 0;
let numTwo = 1;

let movesTaken = [[0,1],[5,8],[3,2],[4,7],[8,3],[9,8],[5,4],[1,1],[4,4],[3,9],[1,43],[23,6]];

what i've tried to do is achieve a true or false value by using .includes() by using the below code

movesTaken.includes([numOne,numTwo]);

and ive also tried

movesTaken.includes([0,1]);

neither of these options seem to work and only output false, how would i go about testing if these exist in the array? will this leave me with no choice but to use a for loop to loop through each individual sub-array and their individual values?

See this answer from the duplicate

The some() method tests whether at least one element in the array passes the test implemented by the provided function. It returns a Boolean value.

The every() method tests whether all elements in the array pass the test implemented by the provided function. It returns a Boolean value.

I think you can use something like this

let array = [0, 1];
let movesTaken = [[0,1],[5,8],[3,2],[4,7],[8,3],[9,8],[5,4],[1,1],[4,4],[3,9],[1,43],[23,6]];
let check = movesTaken.some(a => array.every((v, i) => v === a[i]));

console.log(check);
