Yes, there are right ways and wrong ways, as usual.

No, that could be happening in other languages, BUT NOT IN JAVASCRIPT.

In Javascript both strings on each side of the + operator
are made into a new memory-location that just fits the combined length
and then a pointer is returned to assign a variable to it.
 
If the temporary location of the first string could be enlarged to 
accomodate the appending of the second one, that would be extremely 
wastefull in memory, as Javascript has no limited length for strings, but 
much faster.
