Fixed Size:Arrays passed to functions must have a fixed size matching the parameter definition. Pass by Value:Arrays in Go are passed by value, meaning the original array is not modified unless a pointer is used. Return Types:Functions can return arrays, which can be assigned to variables or...
String 值是可以比较的。 Pointer值是可以比较的。如果两个指针值指向同一个变量那么这两个指针值相等,或者都是nil。 Channel 值是可以比较的。 Interface值是可以比较的。如果两个interface值得concrete type和value都相等(前提是concrete type是可比较的),那么这两个interface相等。如果两个interface都是nil那么也相等。

The len function behaves inconsistently when applied to a nil array pointer in TinyGo compared to standard Go. While Go 1.24.1 returns the array length without a panic, TinyGo produces a runtime error when dereferencing a nil array pointer. $ cat test.go package main func nilPtrToArray() ...
In Go, arrays can be passed to functions as arguments. However, when an array is passed to a function, it is passed by value, meaning a copy of the array is made. To modify the original array, a pointer or slice should be used. ...

go1.17 added the ability to convert from slice to array/array pointer: https://tip.golang.org/ref/spec#Conversions_from_slice_to_array_or_array_pointer However, the UX for this was super ugly until go1.20 (just released): We should now m...
golang 作为 C 语言创始人的作品的一个主要的设计初衷是“减少语言的复杂性”,当初 C++ 的出现不仅仅引入了 OOP、还有 generic programming、exception handling 等等,这一切导致 C++ 被认为是 expert-friendly 的语言。说实在的搞了这么多年的 C++ 程序仍然时常被一些问题困扰的我也比较赞同这个“突破点”。最近两...
The return type of this method is mixed, it returns the array value in the next place that's pointed to by the internal array pointer, or false if there are no more elements. [Source]Note As we have discussed in the previous tutorial (current() function) that an array has a pointer...
