Good day! Stumbled upon such a way to compare two arrays

a1.length==a2.length && a1.every((v,i)=> v === a2[i])

Can you please tell me how to adapt it for comparing two two-dimensional arrays?

    In javascript no two-dimensional arrays. There are arrays consisting of arrays. Well, that and adapt

     function isEqualArray1(a1, a2) { return a1.length === a2.length && a1.every((v,i)=> v === a2[i]); } function isEqualArray2(a1, a2) { return a1.length === a2.length && a1.every((v,i)=> isEqualArray1(v, a2[i])); }

      No length comparison

       a1.every((v,i) => a1[i].every((v,j) => v === a2[i][j]))
