insane
var string = Array();
string.push(part);
string.push(part);
string.push(part);
string.push(part);
string.push(part);

// make sure it doesn't compile out
// costs the pagan compiler gods a function call
noop(string.join(""));
ready
not insane but not advisable
var string = [ part, part, part, part, part ].join("");

// make sure it doesn't compile out
// costs the pagan compiler gods a function call
noop(string);
ready
is it?
var string = part;
string += part;
string += part;
string += part;
string += part;

// make sure it doesn't compile out
// costs the pagan compiler gods a function call
noop(string);
ready
