# For Loop
The easiest form of a loop is the for statement. This one has a syntax that is similar to an if statement, but with more options:
~~~
for(condition; end condition; change){
// do it, do it now
}
~~~
Lets for example see how to execute the same code ten-times using a `for` loop:
~~~
for(var i = 0; i < 10; i = i + 1){
// do this code ten-times
}
~~~
> ***Note***: `i = i + 1` can be written `i++`.
Exercise
Using a for-loop, create a variable named `message` that equals the concatenation of integers (0, 1, 2, ...) from 0 to 99.
~~~
var message = "";
