javascript - 将大字符串分成几部分

Question

我有多个字符串如下 -

var str1 = "this is a test that goes on and on"+param1
var str2 = "this is also a test this is also"+param2+" a test this is also a test this is also a tes" 
var str3 = "this is also a test"

我将每个字符串分配到它自己的 var 中，以保持代码的可读性并防止字符串值尾随字符串。另外，正如我所读到的，换行符 javascript 字符不适用于所有浏览器 - Creating multiline strings in JavaScript

然后我连接字符串 -

var concatStr = str1 + str2 + str3

并返回字符串连接值。

这是将大字符串分解成多个部分的可接受方法吗？还是可以改进？

无需将每一行分配给不同的变量:

var str1 = "this is a test that goes on and on"+param1 +
     "this is also a test this is also"+param2+
     " a test this is also a test this is also a tes" +
     "this is also a test";

就我个人而言，我会执行以下操作:

var string = ['hello ', param1,
              'some other very long string',
              'and another.'].join(''); 

对我来说，打字和阅读更容易。
