在go中应该使用什么New（）或var？

Question

How a object should be created for a struct?

object := new(struct)

or

var object struct

I could not understatnd when to use what? and if both are same which one should be prefered?

Answer 1

When you need a pointer object use new or composite literal else use var.

Use var whenever possible as this is more likely to be allocated in stack and memory get freed as soon as scope ends. I case of new memory gets allocated most likely in heap and need to be garbage collected.
