# Loops

### While Loops

While loops will be executed WHILE the condition is still true.

{% code lineNumbers="true" %}

```
while true == true then
    log("True is equal to true (No way!).")
end
```

{% endcode %}

### For Loops

For loops will repeat a block of code for a set number of times. It will count a variable from a start point to an end one. An optional step controls how much the counter changes iteration (default is 1, use a negative step to count down).

{% code lineNumbers="true" %}

```
-- Count up from 1 to 5
for i = 1, 5 then
  log(i)
end

-- Count down from 10 to 0 by 2
for i = 10, 0, -2 then
  log(i)
end
```

{% endcode %}
