Libya
The flag of Libya, until 2011, was a simple green rectangle.
Try the program as it is given, then change it so that the green rectangle is 150 wide.
function drawFlag(ctx) { ctx.fillStyle = 'green'; ctx.fillRect(0,0,75,100); }
function drawFlag(ctx) { ctx.fillStyle = 'green'; ctx.fillRect(0,0,150,100); }
France
The flag of France is blue, white and red.
The code given draws only one of the three rectangles required and it is in the wrong place.
function drawFlag(ctx) { ctx.fillStyle = 'blue'; ctx.fillRect(50,0,50,100); }
function drawFlag(ctx) { ctx.fillStyle = 'blue'; ctx.fillRect(0,0,50,100); ctx.fillStyle = 'white'; ctx.fillRect(50,0,50,100); ctx.fillStyle = 'red'; ctx.fillRect(100,0,50,100); }
