Loops

There are 4 basic and 1 special types of loops in TaffyScript.

Note: on all of the examples, I put the loop body in curly braces. If you have a simple (one-line) statement, you don't have to do that. For more complex bodies, it is still necessary.

Basic Loops

Repeat

A repeat loop has the following form:

repeat(number) {
    //body goes here
}

number can be a constant or an expression that results in a number. The code in the repeat body will execute the specified number of times.

While

A while loop has the following form:

while(condition) {
    //body goes here.
}

The code in the while body will continue to execute while the condition is true or a break statement is hit.

Do Until

A do-until loop has the following form

do {
    //body goes here
}
until(condition)

The code in the do body will continue to execute until the until condition is true. Unlike a while loop, the do-until loop will always execute at least once.

For

A for loop has the following form:

for(init ; condition ; increment) {
    //body goes here
}

This loop is obviously a bit more complicated. First, the init segment is executed. Then, while the condition is true, the body executed. After each execution of the body, the increment code is run. A better example:

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

The init segment is optional, but the condition and increment parts are mandatory.

Continue

If the code hits a continue statement in any loop, it stop executing the current iteration of the body and move directly on to the next. For example, the following code uses continue to only output even numbers:

for(var i = 0; i < 10; i++) {
    if(i % 2 == 1) {
        continue;
    }
    print(i);
}

Break

If the code hits a break statement in any loop, it will stop all execution of the current loop.
