For other languages there are many variables when it comes to writing code. Every language is good for its use case, but Go is a little special because it was designed at a company which is the very synonym of the Internet (and distributed computing). Typically in order to optimize programs, developers choose to write Java over Python and C++ over Java, but almost all available languages widely in use were written decades ago when 1GB storage was much pricier. Now storage and computing is relatively cheap and computers are getting multiples cores, but the "old languages" are not harnessing concurrency in a way that go does. It's not because those languages are bad; utilizing concurrency wasn't a relevant usecase while the older languages evolved.
To mitigate all the problems that Google faced with current tools, they wrote a systems language called Go which you are about to learn! There are many advantages to using golang and there are disadvantages too, for every coin has both sides. One of the significant improvements in in code formatting. Google has designed the language to avoid debates on code formatting. Go code written by anyone in the world (assuming they know and use `gofmt`) will look exactly the same. This won't seem to matter until you work in a team! Also when the company uses automated code review or some other fancy technique, the formatted code may break in other languages which don't have strict and standard formatting rules, but not in go!

Go was designed with concurrency in mind, please note that parallelism != concurrency, there is an [amazing post](https://blog.golang.org/concurrency-is-not-parallelism) by Rob Pike on the [golang blog](https://blog.golang.org/), you will find it there, it is worth a read.

Şimdi daha iyi gibi.`:=` kullanarak `var` ve `type` ihmal edilebiliyor, buna öz ifade deniyor. Ama bir dakika, tek bir şart var: bu yöntemi sadece fonksiyon içinde kullanabilirsiniz. Fonksiyon gövdesi dışında kullanırsanız derleme hatası alırsnız. Bundan dolayı, global değişkenler için `var` kullanıyoruz ve kısa tanımalar içinde `var()` anahtar kelimesini.
`_` (boş) özel bir değişken ismi. Verilen her değer yoksayılır. Örneğin, `35`değerini `b`'ye' atıyoruz ve`34` değerini yoksayıyoruz.( ***Bu örnek sadece nasıl çalıştığını gösteriyor. Genelde fonksiyonlardan dönen değerleri yoksaymak iiçin kullanıyoruz*** )

## 插入数据
下面的代码演示了如何插入一条记录，可以看到我们操作的是struct对象，而不是原生的sql语句，最后通过调用Insert接口将数据保存到数据库。
