Talk:String append: Difference between revisions

:If you look at the code on this page, almost none of the languages are actually operating "in-place". They are all variants of <code>s = "foo"; s += "bar"</code>, which in the underlying language implementation almost certainly allocates <code>"foo"</code>, then allocatesand <code>"bar"</code>, then allocates a third string and writes <code>"foobar"</code> to it (unless the whole thing is constant-folded at compile time). The fact that only a single named string variable <code>s</code> is used is merely a syntactical illusion. [[User:Stevengj|— Steven G.
