2. Questions on JavaScript How were these done? What JavaScript features? –date at top of page –rollover image swap –slide show –status line –coffee shop –'virtual dog'

3. Hint Remember: your names need to be consistent; JavaScript (DOM) names need to be correct! Use the Edit/Find to go through text and check on names

4. Hint The rules for JavaScript are that { } can replace a single statement The official format is if (condition) statement; So this is usually if (condition) {statements} Use the brackets even if you only have one statement.

5. Hint The plus operator does addition of the operands are numbers or concatenation if the operands of strings. The asterisk operator always does multiplication, converting strings to numbers, if required. Contents of form input tags are strings. If the input is to be considered a number, the code needs to do something to make it a number.
