HTML5 Canvas Tutorial: Rotation, Stars & Polygons

Drawing stars, polygons and triangles with vanilla JavaScript and HTML5 canvas can be easy. Let me show you my favourite technique. In this tutorial we will write a single function that can draw 100 different shapes. We will learn how to rotate shapes using built in HTML canvas methods save(), restore(), translate and rotate() and we will learn everything we need to know about drawing lines and shapes with beginPath(), moveTo() and lineTo() methods. All of that with plain vanilla JavaScript with no frameworks and no libraries. We are here to create cool things, but we also want to learn how things work under the hood and really understand the code. We will also use that knowledge to create multiple creative coding projects (generative art paint brush). Join me and let's draw 100 different shapes with JavaScript.
