I have such a problem. I need to create a pair of functions for saving and loading matrices to and from text files.

1. I need to creat a fnction saveMatrixToFile(matrix, path), that writes the contents of the argument matrix into a file located at the given path.
2. then to create a fnction loadMatrixFromFile(path) function, that returns a matrix filled with the contents of a file that has been created using the saveMatrixToFile() function.

Here is a part of my code, but I'm not sure if it's right or not.

const fs = require('fs');
function saveToTextFile(matrix) {  
fs.writeFile("./new.txt", matrix, (err) => {
    if(err){
        console.log(err);
    }
    else {
        console.log("saved to textfile1");
    }
});

console.log("next");
}
