Interactive Quiz ⋅ 11 Questions
By Stephen Gruppetta

In this quiz, you’ll test your understanding of JavaScript Loops for Pythonistas.

By working through this quiz, you’ll revisit the Python loop habits that misfire in JavaScript: what for...of and .forEach() hand you, how a counting loop’s counter behaves, what a do...while condition can see, how .entries() and Object.entries() give you pairs, what .find() returns when nothing matches, and how to leave two loops at once.

Most questions show a short snippet and ask what it does when it runs, so you can check that your Python habits won’t slip into your JavaScript. Good luck!

The quiz contains 11 questions and there is no time limit. You’ll get 1 point for each correct answer. At the end of the quiz, you’ll receive a total score. The maximum score is 100%. Good luck!
