Drupal 8.x

I am trying to add AJAX functionality to a webform in Drupal 8.4 that will copy address information from one section to another. 

The first set of fields for business information is as follows:
- Address 1 (textfield)
- Address 2 (textfield)
- City (textfield)
- State (textfield)
- Country (select)

The second set of fields for shipping information is:
- Information same as business (checkbox)
- Address 1 (textfield)
- Address 2 (textfield)
- City (textfield)
- State (textfield)
- Country (select)
