How to use stroke

Answer 1

The stroke() method actually draws the path you have defined with all those moveTo() and lineTo() methods. The default color is black.

Answer 2

yes anil Krishna raj told correctly but it is not in svg it is in canvas
you can use Stoke() methods with arguments as coordinates of end point width and color
you can call it using scripts

in svg you can use Stoke as attribute to set color of outlines of vector and also none to remove it

Answer 3

Anil Krishna raj is right 😉
