title: How to apply shaders to canvas (javascript)
body: <p>I have <strong>no</strong> experience with shaders at all. Not in javascript neither in any other language. I have seen shaders in JS with ThreeJS.</p>
  
  <p>I would like to use shaders to manipulate parts of canvas for audio visualization, using bass filter and shaders. I did manage to get data from bass filter, but haven't got any clue how nor where to find good tutorials with shaders in vanilla JS, or some light weight framework.</p>
