ruby on rails - Use \ instead of + or << to concatenate those strings -

-

I'm using RookOp to clean my dirty code ...

A There were errors:

use

instead of + or

Why is that so?

I can not find it. + or & lt; Why would I use the \ instead of

= "post-text" itemprop = "text">

ruby In, virtual wires are allocated as objects in memory, when they come in front. If you add two string literals, like 

  str = "foo" + "bar"

you will actually assign three strings Objects: "foo" , "bar" and combination result (which is then referred to by str )

It is as if you do: 

  "foo" & lt; & Lt; "Bar"

In many cases, this is only a light inability that you should not worry too much.

However, keep in mind that if you do this, a loop, and if the total string gets bigger, then you should use an ever greater string < / Code> will assign objects (even if you call it string parts as aaa , and then call ; foo foo

\ in' you can not add intermediate objects, but instead the parser has a string > literal (because \ is just continuing the string on the next line).

"foo" + "bar" + "baz"
