Just a beginner tip. Many programmers still use
string concatenations in the classical way. An example situation like this -
Adding and deleting div dynamically in JavaScript[

Are JavaScript
strings mutable? NO. So what is the best way to concatenate
strings in JavaScript like runtime markup generation, etc? The .NET way is to use
StringBuilder. From Framework 3.5, it is available through the Microsoft Ajax Library. Enable Ajax in the page by using a
ScriptManager. Now the
Sys.StringBuilder class is available for use.
<asp:ScriptManager ID="script1" runat ="server">
</asp:ScriptManager>
In Javascript:
var sb = new Sys.StringBuilder();
sb.append("Hello ");
sb.append("World ");
alert(sb.toString());
How does a
string builder do concatenation efficiently? It uses an
array to hold the
strings, then uses the
Array.Join to concatenate the
strings. So intermediate
string generations are avoided.
