Uncaught TypeError: Cannot read property 'string' of undefined

[vishnukalakota]

could you please fix this error.
this is due to PropTypes is moved from core react
to prop-types

@vishnukalakota I'll take a look at it but unfortunately not soon. in the meantime, you can add this piece of code to the index.jsx or app.jsx of your project:

import React from 'react'
import PropTypes from 'prop-types'

React.PropTypes = PropTypes

Hi,
could you please explain me how the array operations(some, every, filter and map) are evaluated.
i want to apply this logic
{"map":[ {"var":"integers"}, {"*":[{"var":""},2]} ]}
on this data
{"integers":[1,2,3,4,5]}

=> will not be evaluated by JSON logic throwing an error
Thanks
