Google Workflows: How to get part of a string?

Question

In the following workflow I want to return part of a string, for example:

- define:
    assign:
      - value: foobar
- returnValue:
    return: ${value}

This would return foobar how would I return just foo?

Answer 1

This feature is now supported under the text library.

You can get part of the string using ${text.substring(value), 0, 3}
