How do I know if spreadsheet cells are merged using google apps script

Question

In a Google docs spreadsheet. If cells A1 & A2 are merged, is there a way to confirm they are merged, using google apps script?

There is a merge function in GAS

Answer 1

For those like me who didn't know the .breakapart() method to unmerge cells: https://developers.google.com/apps-script/class_range#breakApart

Thanks to Henrique for the tip !
