Leaflet Polyline\Polygon explanation

I want to know what is the meaning of the following list of coords.
I printed to the console my polyline and get this list:
175.2754282951355 -37.77071473849609,175.2665877342224 -37.77156281398483,175.2675747871399 -37.77478541213123,175.27753114700317 -37.77380168653865,175.27602910995483 -37.77085043122794
you can get it as string.
if I want to define an object of type polygone, how to insert this list to get back my polygone on my map?
thanks!
