Cannot add key if there is no element inside loop about babel-plugin-transform-react-pug

[ezhlobo]

@wulunyi hey, just was thinking, that item can be an element in your case. So you have to do it properly according to what react says:

pug`
  each item, index in tags
    = React.cloneElement(item, { key: index })
`

Anyway, be careful with using a key as an index from the array.

@wulunyi what is the reason to do this? Could you show an example of what you need in jsx?

Both of following examples work with well:

each item in tags
  = item

each item, index in tags
  p(key=index)= item
