Iterate Json ResponseText in Coffeescript

My CoffeeScript

errorList = @state.errors.responseText
  for own key, value of errorList
    console.log "#{key} -> #{value}"

My errorList variable={"link":["is invalid"]}

When I run this code, in output iterate each char in this errorList. How Can I get "link -> is invalid" ?

It seems that your responseText property is a String, which isn't yet an iterable Object. To convert this (valid) JSON String to an Object we can iterate, you should call JSON.Parse.

The following should work in your case

errorList = JSON.parse @state.errors.responseText
  for own key, value of errorList
    console.log "#{key} -> #{value}"

Output:

link -> is invalid
