This article will mention what Loops are.
In Loops. there are three types loops which are Loop List, Loop Forever, Break.
Loop List gets an array and works once for every item of the array. You can add nodes to Loop List.
It takes Items value and Variable Name value. You must enter an array to Items and string value to Variable Name. you can get each value of the array with the value you entered to Variable Name.
Loop Forever works non-stop until Break node works. You can add nodes to Loop Forever.
When Break works, the flow stops.
