Core Syntax & Patterns
The 'If...Then...' Pattern
IF [a condition is true], THEN [do an action].
Use this to make a decision. First, check the 'If' part. If it's true, you must do the 'Then' part.
The 'Do Nothing' Pattern
IF [a condition is NOT true], THEN [do nothing].
If the 'If' part is not true, you just skip the action. You don't have to do anything!
