I don't know why there is ERROR in my code

Answer 1

Read the error message carefully: You did not define any variable or constant with the name "Context". Hence it is unclear what "Context" refers to.

You may work with canvas, first of all you need to create a <canvas> with a specific width and height and id, then select the canvas with its I'd and save to your Context variable.
Remember onclick event is not work as write it, the event should capture throw an event listener call back function.
