在Go中初始化结构时使用new与{}

Question

So i know in go you can initialize a struct two different ways in GO. One of them is using the new keyword which returns a pointer to the struct in memory. Or you can use the { } to make a struct. My question is when is appropriate to use each? Thanks

Answer 1

I prefer {} when the full value of the type is known and new() when the value is going to be populated incrementally.

In the former case, adding a new parameter may involve adding a new field initializer. In the latter it should probably be added to whatever code is composing the value.

Note that the &T{} syntax is only allowed when T is a struct, array, slice or map type.
