Use Join and Array in ASP to speed up character connection. Code _ javascript skills

In ASP, Join and Array are used to speed up the character connection. Today, I saw a lot of test data on the Internet, so I was too lazy to read it and copied the conclusion.

For example
<%
Dim a (10000), I, t
T = Timer
For I = 0 to 10000
A (I) = CStr (I)
Next
Response. Write Join (a, vbCrLf)
Response. Write timer-t
Erase
%>
Speed can be combined with php (although it is still not fast), another use is s = Join (Array ("1", "2 ", "3 ",....., "9999 "))
The speed is still much faster than "1" & "2" & "3" &... & "9999"
