Lesson 1 — console.log
Seeing output
console.log(...) prints whatever you pass it to the browser console — the developer window where JavaScript talks back to you. Open the Console tab and press Run to see it.
Why it matters: logging is the first tool every JS developer reaches for to check values and debug.
Tip: you can log several things at once: console.log("score", 10).
