B4J Question string join?

[Darsiar]

Hello!
We carefully study the language, and probably we don’t see something!
We cannot find such an important operation for joining the lines "+" or "&":
dim s as string = "aaa" + "ddd" + "ccc"
s = s + "eeee"

Or maybe?
dim s as string = "aaa" & "ddd" & "ccc"
s = s & "eeee"

In all languages, including js and Basic *** this is the minimum standard, without which the initial operation with texts is simply not possible!

Maybe there is a library or a secret method which is not in the textbook?
How can this be so that we do not find such a simple action?

thank

Read the guides: https://www.b4x.com/learn.html

Have you tried it:

dim s as string = "aaa" & "ddd" & "ccc" 
Log(s)

?
It will work.

Thank you so much, Erel!
It works.
They themselves are surprised that they did not find it in the textbook.
