Hi,

Under most languages it pays to use a StringBuffer of sorts.

Is this true for Ruby, should one use a StringBuffer when appending
many strings?

If so, what is the string buffer called for Ruby?

Strings are mutable in ruby so you just use the << method to append to a
string. Don't, though, use + as that creates a new string.

'Foo' << 'Bar', etc

Under most languages it pays to not do heinous things that cause the
interpreter/runtime to thrash.

Thanks very much, this looks like a very useful resource.

Thanks, I will give that a go. My automatic knee-jerk reaction was to
use +=, as you pointed out, looks like some more syntax to adjust to
here!
