looping

The script feature provides for both while and for looping. These take on the same syntax that a for or while does in java, C, or JavaScript.

Note: there is no break directive.

for loop

The for loop is used when you know in advance how many times the script should run.

for (var=startvalue;var<=endvalue;var=var+increment) 
{
    code to be executed
}

for (var i = 0; i < array.length; i++) {
  // do something
}
       
var i = 0;
for ( ; i < array.length; i++) {
  // do something
}

while loop

The while loop is used when you want the loop to execute and continue executing while the specified condition is true.

while (condition is true)
{
    //code to be executed
}

var foo = 0;
while (foo < 5) {
  // do something
  foo++;
}
var done = false;
while (!done) {
  // do something
}
