1for vs while — Use for when you know how many times to repeat, like 10 times. Use while when repeating depends on a condition that can change, like until the user types quit.
2infinite loop — A while loop whose condition never becomes False, often because the loop variable is never updated. Stop it with the Stop button, or fix it by changing the variable inside the loop.
3def — Makes a Python function, like defining a Scratch My Block once. Run it any time by calling its name, e.g. greet(). Inputs become parameters, so you reuse the code instead of copying blocks.
4return — Hands a value back to the caller so it can be stored in a variable or used in a calculation. print() inside a function only shows the value on screen, and the function then gives back None.
5if is_even(n): — Calls a function that returns True or False right inside an if condition. The indented code runs only when the function returns True, so no extra variable is needed.
6while guess != secret: — The loop at the heart of a guessing game. It keeps asking until the guess matches the random secret number. If/elif/else gives hints and a counter adds 1 each turn.
7if ask(q, a): score += 1 — Calls a function that returns True for a right answer, then adds 1 to score when it does. Put this in a loop to ask every question and total the quiz score.
8JavaScript — A text-based language where each block you snapped together becomes one line of code that you type exactly, and the computer follows it literally.
9console — The panel beside the editor where your program's output appears after you press Run. Each console.log shows in order, and you run the program again after every change.
10let score = 0; — A statement is one instruction in JavaScript, usually written on its own line and ended with a semicolon (;). This line is one statement.
