Why the browser is ignoring new empty lines inside the textarea in HTML?

When I try to put text that has multiple empty lines inside a textarea in HTML, the browser ignores them and does not display them. My purpose is to allow the user to edit his text while preserving all the new lines.

If I put this:

text a\n\n\ntext b\ntextc  

The browser displays:

text a
text b
text c

My purpose:

text a


text b
text c
