Variable:

This is a “container” for whatever we assign it.  We can assign numbers, words (known as “strings” in Javascript), lists, functions or other “objects” (yet to be discussed) to a variable.  Some examples of this are below:

var x = 1; //an integer

var myword = “hello”; //a single word

var mylist = [“Retriever”, “Hound”, “Mastiff”, “Beagle”, “Terrier”]; //a list of dog types

var draw = function() {

                //put some code here that will be drawn with every screen refresh

}; //in this case we assigned a function to a variable

Loops:

We use loops to perform repetitive work.  The loop usually continues until a condition is met.  Some loops (like the draw() function if defined), will loop endlessly.

This is an example of a “for” loop.  The for loop continues “for as long as the condition is true”.

for ( var i = 0; i<10; i++) {

                println(i);

}

Conditionals:

Conditionals allow us to make decisions and perform different code based on the outcome.  For example:

                var x = 10;

                if(x < 10)  {

                                println(“x is less than 10”);

} else {

            println(“x is greater than or equal to 10”);

}
