ES6 in example

[mantagen]

Students aren't expected to know about es6, so including it in passing is probably unhelpful.

// [] -> []
function makeSoundObjects (sounds) {
  return sounds.map(soundSrc => new Audio(soundSrc))
}

var soundObjects = makeSoundObjects(sounds)

Students of FAC11 have then used ES6 syntax themselves. This is not ideal, before they've been made away of when to use it and when not to

It looks like this was fixed a while ago, so can probably be closed

Edit: found the commit! (this is why calling them all "update readme.md" is unhelpful :P)
