canvas drawing in synchronous so when you draw like this

 canvas.getContext('2d').fillRect(25, 25, 100, 100);

the next line get excuted when the drawing is finished so you can do what you wanted to do after drawing like this

canvas.getContext('2d').fillRect(25, 25, 100, 100);
//draw finished do something
