you even invent your own format.
Then you realize that being locked into one programming language sucks, so you move to using a widely supported, language-agnostic format like JSON (or XML if you like to party like it's 1999 ).
Then you decide that JSON is too verbose and too slow to parse, you're annoyed that it doesn't differentiate integers from floating point, and think that you 'd quite like binary strings as well as Unicode strings. so you in

How come I prefer the first one ?, But not the second one? I thought the first one is faster because it wocould only join rows which product_name is 'p001' in table [order_detail].

This is also why C # recommends implementing dispose and does not recommend implementing the destructor. Because the Destructor has a high performance cost. Developers of small and medium-sized projects may not feel this, but I believe that those who have worked on large projects will have a deep understanding of the performance of the C # destructor.
In summary, the C # parser is a C # designer who simply wants to show off their own rich syntactic sugar, acc
