How to reuse the WebGL context within a canvas?

I am trying to clear the contents of WebGL canvas.

Is it fine if I just delete the canvas element from DOM and create a new one, and most importantly, will it clear up all the resources and not cause any memory leak.

My scenario is that, I am getting images continuously via AJAX polling from the server every 20 seconds and using a hidden WebGL canvas to draw it and further using another canvas to show it perfectly.

Suggestions?

Basically no, if you just delete the canvas from the DOM there is no guarantee it will get freed in time to create a new one, after 8 or 16 of them you'll possibly get an error.

see How do I clean up and unload a WebGL canvas context from GPU after use?

Why can't you just keep reusing the same canvas or canvases?
