Solutions

var fs = require('fs');
class Reader {
  main() {
  }
  readFile(file) {
    return fs.readFileSync(file);
  }
  saveContentsToFile(file, contents) {
    fs.writeFileSync(file, contents);
    return "good job";
  }
}
module.exports = Reader;

• es5 (current)

var fs = require('fs');
function Reader() {
  this.main = function() {
  }
  this.readFile = function(file) {
    return fs.readFileSync(file);
  }
  this.saveContentsToFile = function(file, contents) {
    fs.writeFileSync(file, contents);
    return "good job";
  }
}
module.exports = Reader;
