Do's

Don't catch errors in the first place

Not catching an error is perfectly fine, if it's something that shouldn't happen just let it fall through and cause a 500 so we know to fix it

Mapping errors

Most of the time when you catch an error you want to map from an infrastructure

  canvas.style = 'position: fixed; top: 0; right: 0; z-index: -100;'


  // const canvas = document.getElementById('background');

  function charRange(start, len) {
    let chars = [];
