Example

In this example, we will pass the required parameters to the function transformation object using a Variables object.

Where,

pattern = (Mr|Mrs).

searchIn = John Antonio, Mr.

replaceWith = student

startAt = 5

In the output window, you can see that Astera has returned a string value with the appended replaceWith value, as the specified pattern value was matched with the searchIn value, after the specified startAt position.
