# Loop
Repeat actions in a controlled way using the **Loop** flow component:
> You can select the Loop Type and the Data you want to loop over, mapping it from previous flow steps.
* **Loop N times**: Run a block a fixed number of times.
* **Loop over data**: Iterate through each item in a list.
* **While loop**: Keep looping as long as a condition is true.
Use **End Loop** to mark where the loop finishes.
In the example shown, the **Loop Type** is set to *Loop over data,* and the **Loop Data** field is mapped from a previous step:
```
{{steps.sendMessage.output.message.blocks}}
```
This means the loop will go through each `block` inside the `message` output from the `sendMessage` step, allowing you to process every block one by one.
