To draw a line using HTML5 Canvas, we can use the beginPath(), moveTo(), lineTo(), and stroke() methods.
First, we can use the beginPath() method to declare that we are about to draw a new path. Next, we can use the moveTo() method to position the context point (i.e. drawing cursor), and then use the lineTo() method to draw a straight line from the starting position to a new position. Finally, to make the line visible, we can apply a stroke to the line using stroke(). Unless otherwise specified, the stroke color is defaulted to black.
