What type of variable is typically used to handle multiple values in Flow Designer?

In Flow Designer, when handling multiple values, an array variable is the appropriate choice. An array is a data structure that allows you to store a collection of items, which can be of the same type or different types, making it ideal for scenarios where multiple values need to be processed together.

Using an array variable in Flow Designer enables you to efficiently manage lists of items, such as multiple email addresses, names, or any set of relevant data. This allows for operations that involve all items within the array, such as iterating through each item, applying conditions, or performing batch processing.

While a string variable may be suitable for single textual data, it does not support multiple distinct values. An object variable can contain complex data but is typically used for structured, key-value pairs rather than lists. A number variable is specifically used for numerical data and cannot handle collections of values either.

Hence, the use of an array variable is essential in Flow Designer for efficiently managing and manipulating multiple items within workflows.
