JavaScript Large string connection StringBuffer class _javascript tips

A large string connection is best done by using arrays, putting each substring into an array element, and then performing a join () connection, which is significantly more efficient than + =.

Therefore, you can write a simple StringBuffer class from this principle, which can be useful when you encounter a large string connection.

function StringBuffer () {
This.data = [];
}
StringBuffer.prototype.append = function () {
This.data.push (Arguments[0]);
return this;
}
StringBuffer.prototype.toString = function () {
Return This.data.join ("");
}


Or maybe that's okay.

function Method2 ()
{
var result = "";
var a = new Array ();
for (var i=0; i<totle; i++)
{
A[i] = str;
}
result = A.join (""); A=null;
return result;
}
