Angularjs leaflet polyline / polygon plotting

May I ask how do I plot polyline based on the array I have?

I have a nested array that look like this

$scope.polyLineCord = [ 

[ "1.31069258855609,103.848649478524", "1.31138534529796,103.848923050526",
  "1.31213221536436,103.848328363879" ........ ],

[ "1.31325347115021,103.875033701234", "1.31345328024369,103.875709799178",
  "1.31385830012311,103.876965410503" ........ ]

];

How do I plot something like that on map ? I have a nested array of 2 polygon

Please and thanks for the help!
