How to compare the contents of two .js files using node js

I have two .js files with several functions defined in them and I wish to compare the contents of these two files. Is there an npm package for such a comparison or any other way to do this?

You just need to compare them as if they were 2 plain text files. You could do something like this:

function readFile(name) {
    return new Promise((resolve, reject) =>
        fs.readFile(name,  function (err, data) {
            if (err) { reject(err); }
            resolve(data);
        });
    });
}
Promise.all(readFile('file1'), readFile('file2')).then(data => {
  var file1 = data[0];
  var file2 = data[1];
});
