The isArray task checks if an input is an array and returns a boolean (true or false) indicating whether the input was validated as an array.
Use the isArray task when you need to validate whether a dataset is an array. It is commonly used after a task that does not have a constant outgoing variable type — for example, an external API request that could return either an array or a string.
The arr variable is statically set to ["1","2","3"].
The outgoing result is true, indicating the input is an array.
The arr variable is set to "1","2","3" — notice the square brackets [] are missing from the beginning and end of the value.
The task returns false, indicating the input is not an array.
