The document compares two vocabulary quiz games - an SAT vocab game and a Harry Potter trivia game. The SAT vocab game uses arrays, functions, and randomizes questions, while the Harry Potter game uses preset questions in alert boxes. The author created the SAT vocab game over 6 weeks with help from others, using HTML, CSS, JavaScript, and jQuery. They created the Harry Potter game alone in the last week of a 12-week JavaScript class using only JavaScript. Going forward, the author wants to add multiple choice answers and refine definitions to their SAT vocab game.
