HTML Canvas DEEP DIVE for Beginners

Creating beautiful interactive animations for the web can be easy. HTML canvas allows dynamic scriptable rendering of 2D shapes and bitmap images and we can also make games using those same techniques. We can draw shapes with code and in this HTML canvas deep dive for beginners we will use vanilla JavaScript to draw a single line, and then we take it to the next level! There are a lot of things you can do with lines, for example create a fully interactive self animating vector field that reacts to used input in multiple different ways. Have fun ❤
