padStart Task Purpose
The padStart task is used to pad a current string with a specified string (repeated, if needed) so that the resulting string reaches a given length. The padding is applied at the start of the current string.
Potential Use Case
Suppose you have a dataset of a known length and you would like to repeat that dataset at the beginning of the current dataset. You could use the padStart task to specify the numeric length and variables needed to "pad" or be added at the start of the original dataset.
Input and output parameters are shown below.
||String||Required. The string to pad.|
||Number||The length of the resulting string after it has been padded. If the value is less than the original
||String||Required. The specified string to pad to the start of the original string.|
||String||A string that has been padded at the beginning with a specified string to the desired length.|
In this IAP example:
strvariable is "Hello World" and the current length of the string is 11 characters, including the space.
targetLengthhas been set to 14, and the
padStringvariable of "123" is applied at the start of the current string so that it reaches the desired
targetLengthof 14 characters.
The expected end result is "123Hello World". Notice that the beginning of the word string for "Hello World" has been padded with "123" in order to fulfill the specified
