Remove First

Removes the first item from an array.

Inputs

flow: The flow to execute this node.
array: The input array to remove the first item from. Defaults to an empty array.

valueType: The type of the array items. Can be one of: string, number, float, boolean, object, array. Leave blank to auto-detect.

Suppose you have an array of names and you want to remove the first name from the list:

["Alice", "Bob", "Charlie", "David"]

You can use the Remove First node to accomplish this:

Connect the array to the array input of the Remove First node.
Leave the valueType configuration blank to auto-detect the item type as string.
The output will be the array with the first item removed:

["Bob", "Charlie", "David"]

If the input array is empty, the Remove First node will have no effect.
The Remove First node modifies the input array in place. If you need to preserve the original array, first make a copy of it using the Duplicate node.

Forgetting to set the valueType configuration can lead to unexpected results if the array items are not of the auto-detected type. Always double check this setting.
Connecting a non-array value to the array input will result in an error. Ensure you are passing a valid array.
