- 1. An error shown when code breaks JavaScript's rules, like a missing quote, bracket or brace. JavaScript can't read the code, so the program won't run until you fix it. (11)
- 4. Uses a function that returns true or false directly as the if condition, so the code inside runs only when the call ______(______) gives back true. Word 2 of: if (_______(___)) (7)
- 7. Part of an error message: the file and line number where JavaScript noticed the error. Check that line first, but the real mistake may be a line earlier. Word 1 of: ______.js:3 (6)
- 8. Word 2 of the term in 5 Down: ___ ______ = ______(4); (6)
- 9. Word 3 of the term in 4 Across: if (_______(___)) (3)

- 2. Separate several parameters with commas. A call like ______(2, 3) must give one argument for each, in the same order. A missing argument becomes undefined. Word 2 of: function ___(a, b) { (3)
- 3. Hands a value back to the code that called the function so it can be stored or used. console.log only shows a value in the console, so a function that only logs gives back undefined. (6)
- 5. A function call is replaced by the value it returns, so you can store it in a variable, print it or use it in a calculation like ______(2) + ______(3). Word 3 of: ___ ______ = ______(4); (6)
- 6. Word 1 of the term in 5 Down: ___ ______ = ______(4); (3)
- 7. A function can use if and else to make a decision, then return a different value from each branch. A default return at the end covers every other case. Word 2 of: if (_____ >= 80) { ______ "A"; } (5)
