用GO语言对切片，通道和地图进行分配和直接分配有什么区别
问题描述：
I'm new to go language, look this code section
a := make(map[string]string, 10)
a["name"] = "Blob"
// or
b := map[string]string{}
b["name"] = "Blob"
Questions:
Does "make" allocate memory on heap?
Does the "make" function only add one step to the initialization operation? like combination of malloc and memset in C language?
我是新来的语言，请查看此代码段 p>
a：= make（map [string] string，10）
a [“ name”] =“ Blob”
//或
b：= map [string] string {}
b [“ name”] = “ Blob”
code> pre>
问题： p>
“ make”是否在 p>
“ make”函数是否仅在初始化操作中增加了一步？ 像C语言中的malloc和memset的组合？ p>

答
The difference is that make(map[string]string, 10) provides a capacity hint for the map and the composite literal map[string]string{} does not.
The maps are allocated on the heap in both cases.
The make function allocates and initializes an object as does the composite literal.
