coffeescript stack trace

stack_trace.coffee

  getStackTrace = ->
    stack = (new Error).stack or ''
    stack = stack.split('\n').map((line) ->
      line.trim()
    )
    stack.splice if stack[0] == 'Error' then 2 else 1

  onRender: ->
    console.log("Custom stack trace:")
    console.log(getStackTrace().join('\n'))
    # The following works fine too, you just end up seeing absolutely every call in the stack trace
    console.log("console.trace: ")
    console.trace()
