Before moving on: Write a 150-line Node.js command-line program, such as a quiz or a budget tracker, that uses functions, arrays, objects, reading a JSON file and error handling, without following a tutorial.

Tauseef's advice

Learn the language before React or any framework: people who skip this spend years confused by closures and async code. Type every example, run your code in Node.js as well as the browser, and do not switch languages for three months.
