Step Functions - how to join an array?

0

As of now there is a States.StringSplit($.inputString, $.splitter) intrinsic function to split an string into an array. Is there a way to join an array into an string? Something like States.ArrayJoin($.inputString, $.joiner)? Is there any work around to achieve something like that?

Reason is that I want to replace a character in a string, since there is no replace I thought about splitting and joining which does have the same effect. I'm using an activity and building an url with the taskToken, but unfortunately any "+" character get's replace by a space, so I want to replace it with "%2B".

One option will be to use States.Format() and pass the array contents if the array length is fixed.

    Thanks, unfortunately the output of an taskToken does not have an constant number of "+". I already thought about a loop which combines always 2 array values as long as there are more than 1 value in the array. But for an Standard function that's also pretty expensive. Would be nice if there is a native function to achieve that.
