但在最下面的package.json文件引起了我的注意。从名称上面来看应该是一个存储元数据的文件，到底是不是呢？...我们打开它看一下： image.png 从package.json内容中来看，其存储的不只有metedata，还有很多其它数据。例如版本号，依赖包等等。...如此看来，package.json貌似很重要的样子。那么问题就来了:package.json到底是做什么的？ ...Nodejs官网给出的解释，package.json主要有两个功能： 用来保存工程元数据。 还可以用来描述工程的依赖项。 ...为了深入理解package.json，我们从nodejs官网下载一个完整的package.json示例，如下： { "name": "module-name", "version": "10.3.1
package mainimport ( "fmt")func main() { ch := 'b' fmt.Println(ch/2.0)}答案选C。这道题很容易选A。

package mainfunc main() { m := make(map[int]int, 3) x := len(m) m[1] = m[1] y := len(m) println(...这里关键是 m1 = m1，右边的 m1 返回 0（map 中不存在某个 key 时，返回零值），因此最后 map 中有一个元素：1->0。图片
