Determinant-Solver

In a bid to translate a little machine learning maths into javascript, I thought I'd start off by making a program that solves any nxn determinant via recursion. To break it down a little further it:

Takes an nxn array.
Performs a bunch of error checks to validate input.
If no errors are returned it passes the array into a function that performs the calculation.

Called using an error first callback

e.g


det( [[1,3],[2,4]], (err,res) => {
  if(err){
      console.log(err)
  }
  else {
    console.log(res); //returns -2
  }
 });
 
  

det( [[3,2,1],[2,-1,-3],[-1,2,-4]], (err,res) => {
   if(err){
      console.log(err)
  }
  else {
    console.log(res); //returns 55
  }
});

Mindblowing stuff
