Search for matrix inside another matrix in Js

Question

I wonder if it is possible to identify if a matrix is inside another javascript matrix.

For example, if the matrix A is inside B or C inside A.

I’m trying to apply the following code:

a = [[1,2],[5,4]]

c = [[2,4],[10,8], [1, 2], [5,4]]

function compare(first, last)
{
    var result = first.filter(function(item){ return last.indexOf(item) > -1});   
    return result.length;  
}    

console.log(compare(a, c) === a.length);
