Updated for class 35

[remarcmij]

Summary of updates and improvements:

• Updated npm dependencies
• All exercise code that should not run during a unit test is now placed in a main() function. This simplifies the unit tests and also eliminates the need for global variables which students often use inappropriately (see example below).
• Unit tests now also warns about spurious console.log's
• Corrected spelling for dice exercises: singular die and plural dice
• Fixed some bugs in the test runner and unit tests that cropped up in the class 34 homework

function giveCompliment(/* TODO parameter(s) go here */) {
  // TODO complete this function
}

function main() {
  // TODO substitute your own name for "HackYourFuture"
  const myName = 'HackYourFuture';

  console.log(giveCompliment(myName));
  ...
}

// ! Do not change or remove the code below
if (process.env.NODE_ENV !== 'test') {
  main();
}
module.exports = giveCompliment;
