I created this simple app on Vanilla JavaScript, HTML5 and CSS as a coding test for a job interview.

You can use it by simply dropping the indexcanvas2.html file into a browser window. You do not need to install/download anything.

It does not use npm server

It was my first JavaScript-based app. Hence the code is not of high quality. But it can easily be converted in a VueJS app or whatever framework you prefer.
