A tongue in cheek implementation of hyperscript to illustrating a 'pure ui' approach

hyperscript.js

// Based on http://rauchg.com/2015/pure-ui/
var h = require('hyperscript')

function dashboard(opts){
  // with proper access to the layout data
  // data CSS media queries can be redundant
  if (opts.width > 375) {
    return h('div', 'Twitter followers ' + opts.num)
  } else {
    return h('div', 'Twitter followers ' + (opts.num / 1000) + 'K')
  }
}

console.log(dashboard({ width: 375, num: 400000 }).outerHTML)
