Example 1: Scripts effectively add html code to your document

 

 

 
 

 

 


Example 2: This example printed the message in the alert box when you opened this page...

 

 
 

 

 


Example 3: Using If Statements allow your script to respond to "environmental" conditions of the browse or specific conditions inside your program by conditionally executiong instructions if something is true.

 

 

 
 
 
 

 


Example 4: A common programming construct is the for Loop. This is most often used to handle repetitions tasks, and to generate and regulate autonomous processes.

 

 

 
 

 

 

Example 5: Another version of this same program can be done with the do/while loop.


Example 6: Using Loops and conditional statements together is a key element of many processes you will want to simulate which are not completely uniform (ie. every step of the process is not exactly the same).

 

 

 

Example 7: An example using a for loop with an if and an else if and else statement to do some more complicated formatting.
