why Guil wrapped the err object, in curly braces, as Andrew always passed the Objects as it is ?

Web Development Techdegree Graduate 18,135 PointsHello sir Steven Parker, but in the video it was the err object that was passed from other route after creating it with new Error() constructor, but still when we received it, it should be an object right?

231,236 PointsAssuming you're asking about the place where .render() is called, the error object is being passed inside a new anonymous "locals" object as a property named "err".

Web Development Techdegree Graduate 18,135 PointsSteven Parker, yes so we are passing an anonymous object wit ha property of err(which is an object itself), but what is the reason for doing that, what if we just pass the err object?

.render()
. For more details, see the online documentation for the .render() method.
