The join task is used to join all elements of an array (or an array-like object) into a string.
Potential Use Case
If you have a dataset that is within an array and you want to join this dataset into a string of information, you can do this by using the join task.
Input and output parameters are shown below.
||Array||Required. The array that contains the elements to join.|
||String||Specifies a string to separate each pair of adjacent elements of the array.|
||String||A string with all array elements joined. The task will return an empty string if the length of the array is 0.|
In this example the
arr variable is ["Device1","Device2","Device3","Device4"] and the
separator to use is a comma (" , ").
joinedElements variable that returns is "Device1,Device2,Device3,Device4" with all of the elements separated by a comma (" , ") within one set of double quotation marks.
