Split string with commas to new line

Question

I have a string like

This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day
         


        

Answer 1

> a = 'This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day'
> b = a.split(', ').join('\n')

"This is great day
tomorrow is a better day
the day after is a better day
the day after the day after that is the greatest day"
