Just use replace on string with regex that matches more than one number of occurences of '-' with a single '-'

my_str = my_str.replace(/-{2,}/g, '-')

or a bit optimized for performance one - `my_str = my_str.replace(/-{2,}/g, '-')` which will not replace single `-` with `-` – fanjabi Nov 02 '18 at 14:40
@fanjabi Yes. Thats correct. Thanks for pointing it out. – Vishnudev Krishnadas Nov 02 '18 at 14:43
