If-Else

If/else statements are one of the most fundamental tools in writing scripts. These
statements check to see if a statement is true, if it is true it will perform
a set of actions. If it is not true it will skip those actions and continue to the
next statement until a statement is true or it runs out of statements to check.

Example 1 - Always true

number monthNumber = month(currentDate());
string monthName = formatDate(currentDate(), "MMMM");

if(monthNumber > 0) {
    runnerLog("Example 1: It is the month of " + monthName + "!");
}

Example 2 - Always false

number monthNumber = month(currentDate());
string monthName = formatDate(currentDate(), "MMMM");

if(monthNumber > 12) {
    runnerLog("Example 2: Time no longer exists :(");
}

Example 3 - Sometimes true

number monthNumber = month(currentDate());
string monthName = formatDate(currentDate(), "MMMM");

if(startsWith(monthName, "J") == true) {
   runnerLog("Example 3: This month " + monthName + " starts with the letter 'J'.");
}

Example 4 - If, else-if

number monthNumber = month(currentDate());
string monthName = formatDate(currentDate(), "MMMM");

if(monthNumber == 1) {
    runnerLog("Example 4: There are 31 days this month.");
} else if(monthNumber == 2) {
    runnerLog("Example 4: February is such a wierd month....");
}

Example 3 - If, else-if, else

number monthNumber = month(currentDate());
string monthName = formatDate(currentDate(), "MMMM");
number [] longMonths = {1,3,5,7,8,10,12};

if(arrayElementExists(longMonths, monthNumber)) {
    runnerLog("Example 5: There are 31 days this month.");
} else if(monthNumber == 2) {
    runnerLog("Example 5: There are 28 or 29 days this month. Who knows...");
} else {
    runnerLog("Example 5: There are 30 days this month.");
}
