Question

I have multiple strings as below –

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"

I’m assigning each string into its own var so as to keep the code readable and prevent the string values from trailing across the string. Also as I have read that the newline javascript character does not work in all browsers –
Creating multiline strings in JavaScript

I then concat the strings –

var concatStr = str1 + str2 + str3

and return the string concatenated value.

Is this an acceptable method of breaking up a large string into into its parts. Or can it be improved ?

There’s no need to assign each line to a different variable:

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";

Personally, I’d do the following:

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

For me, it’s easier to type out, and read.
