In contrast, concatenating a string is pretty much just a case of running a single opcode to append a string variable to an existing string variable.
相反，连接字符串操作非常简单，只是运行一个操作码，将一个字符串变量附加到一个现有的字符串变量中即可。
In this case, the function may be called with as many arguments as you wish, and those values are collected into a single variable: an array named a: 000.
在本例中，函数可以使用任意数量的参数调用，并且这些值被收集到一个单一变量中：一个名为a： 000的数组。
In this case, there's a single variable, named people, and the value is the array containing three items, each of which is a person record with a first name, a last name, and an e-mail address.
在这个示例中，只有一个名为 people的变量，值是包含三个条目的数组，每个条目是一个人的记录，其中包含名、姓和电子邮件地址。
