Basics

Operators

• + for addition
• - for subtraction
• asterisk for multiply
• / for divide

these two are the same:

myNum = myNum + 6;
myNum += 6;

• ++ add one
• -- decrease by one

Conditionals

var message = "yellow";                         // the equal sign assigns values to variables
trace ("big " + message + " truck");            // prints "big yellow truck"
if (message == "yellow") {                      // the double equal sign checks to see if variables are equal
trace ("yes, i did say big yellow truck.");     // prints "yes, i did say big yellow truck"
trace (typeof message);                         // prints "string"
var x = a;                                      // prints "number"
trace (typeof a)
}

var x = 1;
while (x <= 5) {                // as long as x is less than 5...
trace (x);                      // return 1 in output
x = x + 1;                      // return 2 3 4 5 in output
}
