Introduction

strokeRect() and fillRect() accept the coordinates of the upper-left corner of a rectangle and its width and height.

The strokeRect() method draws an outline of the rectangle.

The fillRect() draws a filled rectangle.

The following code shows how these methods are used.

        let context = canvas.getContext("2d");
        // draw stuff here
         context.lineWidth = 5; 
         context.fillRect(10,10,180,50); 
         context.strokeRect(10,80,180,50); 
    
            
    };

 <body> 
  <canvas id="myCanvas" width="300" height="200"></canvas>   
 </body>
</html>

Note

You can also use rect() method to draw rectangles.

However, you also need to call stroke() or fill() to actually draw the rectangle.
