What's a DString

[LukyGuyLucky]

May I ask what DString is & why should we need this in addition to String?

Thanks in advance.

It's a dynamic string (i.e. string builder), that is a resizable string which can be appended to at low cost (as opposed to str.concat(str2) which will allocate and copy every time.

Is that just something like StringBuilder type(class) in other language?Thanks.

Yes, or a dynamic string. It has many names.
