Across
  1. 3. Variable Temporary. Can be used only in the part of the code where it was created, like inside an onEvent(). Deleted once the onEvent() is done running.
  2. 4. Operator allows a program to change the value represented by a variable.
  3. 5. Expression evaluates to either true or false.
  4. 7. a named group of programming instructions. Also referred to as a “procedure”.
  5. 10. used to document your code so it is easier for humans to understand.
  6. 13. Error Your code doesn’t follow the rules of the programming language.
  7. 14. Statement affects the sequential flow of control by executing different statements based on the value of a Boolean expression.
  8. 16. A block is used to create event listeners, which allow your program to react to specific events happening in your app.
  9. 17. a named reference to a value that can be used repeatedly throughout a program.
Down
  1. 1. an ordered sequence of characters.
  2. 2. Operator NOT, AND, and OR, which evaluate to a Boolean value.
  3. 6. a combination of operators and values that evaluates to a single value. Expressions are evaluated before storing in variables.
  4. 7. Call a command that executes the code within a function.
  5. 8. Value a data type that is either true or false.
  6. 9. A watcher allows you to “watch” the changing value of a variable while the program is running so you can debug problems.
  7. 11. Operators This is a comparison operator. It’s a clue that we need to STOP and evaluate for a Boolean value.
  8. 12. Variable Permanent. Can be used anywhere in your code.
  9. 15. Error Your code follows the rules of the programming language but doesn’t do what you intend.
  10. 17. Command Tells the computer to create a variable.
  11. 18. Symbol In programming it means “put this value in this variable”.
