Loops

For Each Loop

foreach ($list) {
  each as alias {
    // XanoScript statements go here
  }
}

Parameter	Purpose	Example
$list	The list to iterate through	$users
$alias	The variable to store the item currently being iterated through	user

Place the functions that run as a part of your loop inside {} brackets after defining the alias.

Example

foreach ($x1) {
  each as item {
    util.sleep {
      value = 1
    }
  }
}

For Loop

for (`$loops`) {
  each as index {
    // XanoScript statements go here
  }
}

Parameter	Purpose	Example
$loops	The number of iterations in the loop	10
$index	The name of the index variable	index

Place the functions that run as a part of your loop inside {} brackets after defining the index variable.

Example

for (`10`) {
  each as index {
    util.sleep {
      value = 1
    }
  }
}

While Loop

while (`conditions`) {
  each {
    // XanoScript statements go here
  }
}

Parameter	Purpose	Example
conditions	The condition(s) that the loop will use to determine if it continues to run	`false == false && true == true`

Place the functions that run as a part of your loop inside {} brackets after defining your conditions.

Example

while (`true == true && true == true`) {
  each {
    util.sleep {
      value = 1
    }
  }
}

Break Out Of Loop

break

Example

for (`10`) {
  each as index {
    conditional {
      if (`$index == 5`) {
        break
      }
    }
  }
}

Continue to Next Iteration

continue

Example

for (`10`) {
  each as index {
    conditional {
      if (`$index == 5`) {
        continue
      }
    }
  }
}

Iterating Over an Array of Objects

You can access properties of each item in a foreach loop:

var $users {
  value = [
    {id: 1, name: "Alice"},
    {id: 2, name: "Bob"}
  ]
}

foreach ($users) {
  each as user {
    debug.log {
      value = user.name
    }
  }
}

Nested Loops

You can nest loops for multi-dimensional data:

var $matrix {
  value = [
    [1, 2],
    [3, 4]
  ]
}

foreach ($matrix) {
  each as row {
    foreach (row) {
      each as value {
        debug.log {
          value = value
        }
      }
    }
  }
}

When to Use For vs Foreach

Use for when you need a fixed number of iterations or an index variable.
Use foreach to iterate over each item in a list or array.

Notes on Break and Continue

The break and continue statements work in all loop types (for, foreach, and while). Use break to exit the loop early, and continue to skip to the next iteration.
