How to Toggle A Circle on A Canvas?

5 minutes read

To toggle a circle on a canvas, you first need to create a canvas element in your HTML document and set its width and height. Next, you'll need to use JavaScript to access the canvas element and draw a circle on it using the canvas API. To toggle the circle on and off, you can create a function that will draw the circle when called and clear the canvas when called again. You can use a boolean variable to keep track of the state of the circle, switching it between true and false each time the function is called. This way, you can toggle the circle on and off with a simple button click or event trigger.
